• Could magnets be used for interstellar propulsion?

    I was watching some stuff of magnetic field lines in the universe
    that I recoded last week from zdfinfo.de
    https://www.zdf.de/dokus/geheimnisvolles-universum-100
    It seems those are playing a much bigger role in the forming of galaxies and stars and the 'big bang' in the latest research.

    So that makes me wonder if a spacecraft with just a permanent magnet
    that you can move to give you a force in the direction you want to go
    could be used as a simple fuel-less drive?
    Electromagnets should work too of course.

    Any aliens here that have used it?

    A permanent magnet has a fixed magnetic dipole moment m.

    It would feel a net force F = grad( m B ) in an inhomogeneous
    magnetic field B.

    |Electromagnetic acceleration of permanent magnets 04078 (arxiv.org)
    |by SN Dolya -+ 2015

    from there:

    |The force of the magnetic dipole interaction Fz with the gradient of the |magnetic field can be written as follows:
    |Fz = m*dBz/dz, (1)
    |where m - the magnetic moment per mass unit, dBz /dz - the magnetic field |gradient.

    However, in nature there are no fields that can be used to accelerate
    a spacecraft this way, so one would have to generate such fields.

    Using this:

    gives as first reference:

    Magnetic field lines in galaxies are patterns that represent the direction and strength of magnetic fields, typically following the spiral structure of the galaxy.
    These fields play a crucial role in the dynamics of the interstellar medium and can influence star formation and gas flows within the galaxy.

    N++ West Texas A&M UniversityN++ scholarpedia.org
    Understanding Magnetic Field Lines in Galaxies
    What Are Magnetic Field Lines?
    Magnetic field lines represent the direction and strength of magnetic fields. In galaxies, these lines can be visualized as patterns that trace the magnetic forces at play within the galaxy's structure.

    Structure of Magnetic Fields in Galaxies
    Galactic magnetic fields typically consist of two components:

    Large-scale Ordered Pattern: This mimics the shape of the galaxy, often forming spiral patterns that align with the galaxy's arms.
    Small-scale Random Pattern: This component is generally stronger than the ordered pattern and is more chaotic in nature.
    Measurement Techniques
    Magnetic fields in galaxies are measured using various methods:

    Optical Polarization: Light from stars is polarized by interstellar dust, allowing astronomers to infer magnetic field directions.
    Radio Observations: Synchrotron radiation emitted by cosmic-ray electrons spiraling around magnetic field lines provides insights into the field's strength and structure.
    Zeeman Effect: This method detects frequency shifts in polarized signals from molecules, revealing magnetic field strengths in molecular clouds.
    Observations of Magnetic Fields
    Recent advancements in radio telescopes, like the Very Large Array (VLA), have improved the ability to detect faint magnetic fields in distant galaxies.
    Observations show that magnetic field lines can extend far beyond the visible structure of galaxies, sometimes reaching distances of up to 26,000 light-years.

    Conclusion
    Magnetic field lines in galaxies play a crucial role in their dynamics and evolution.
    They influence star formation and the behavior of interstellar gas, making them a key area of study in astrophysics.

    This corresponds with what the zdfinfo.de series, presented by 2 professors, mentioned.
    So yes, there are magnetic field lines in the universe.

    I know you can use 'gravity assist' to speed up spacecraft to reach further away planets for example
    Why not use 'magnetic assist'?

    I don't know, but it wouldn't be fuel-less: you'd still need energy to
    move the magnet, wouldn't you?

    These natural magnetic fields in galaxies and their gradients,
    I think, are relatively weak. Over long timescales and over larger
    spatial regions, their effects can accumulate and become noticeable.
    But to drive a spacecraft, you'd need fields that are fairly strong
    at the location of the ship and at the moment the ship is there.

    You also need a large _gradient_ of magnetic field. (Unless you have a
    supply of magnetic monopoles :-))

    Thank you, nice link.

    I have been experimenting with diamagnetic magnetic levitation a few years ago:
    https://panteltje.nl/pub/levitation_top_cut_img_3037.jpg
    https://panteltje.nl/pub/levitation_cut_img_3039.jpg

    Magnetism is an interesting subject..
    https://en.wikipedia.org/wiki/Diamagnetism

    In the original TV series that made me think about magnetic propulsion they go back into the origin of the 'big bang'
    they start with neutrons
    those then are broken into electrons (negative) and protons (positive) by beta-decay,
    and those then forms molecules and all sorts of matter and things as we know it and the magnetic fields generated by those elementary particles then form the stars and galaxies, the universe as we know it
    Seems to be the latest science take on the big bang origin.

    Was new to me, those magnetic fields that then form and hold stars and galaxies together are extremely strong they say.
    So pure quantum stuff..

    It means that there is no perpetual motion, no free energy.

    In rectangular coordinates, the gradient of a vector field
    f =( f_1, f_2, f_3 ) is defined by:

    "nabla" f
    = g^jk ("partial"f^i/"partial"x^j) e_i "tensor product" e_k,

    according to the section "Gradient of a vector field"
    of the Wikipedia page "Gradient".

    So, when these derivatices ("partial"f^i/"partial"x^j) are
    large, the gradient is large, meaning the field changes a lot,
    which is need for a significant force on a magnetic dipole.

    Earth has a very weak magnetic field. Consequently even near the poles
    the force will be too small to be of any practical use.

    stars lightyears away.


    And a dipole couples to the field gradient, not the field, so the effect
    would be vanishing**2ly small. (Or is that vanishing**3fly?)

    Earth *is* a magnet. It is pushed by the magnetic fields of the sun and galaxies. That's what makes the earth go round the sun.

    That's why they're worried about magnetic pole reversal.
    We'll start orbiting the sun in the opposite direction.

    A magnet has a north and a south pole.

    Not necessarily. For example, Earth as a magnet has multiple magnetic
    poles, but only two primary ones (where most magnetic field lines end):

    <https://en.wikipedia.org/wiki/Earth%27s_magnetic_field>

    In a uniform magnetic field,

    There is no such thing, or *only approximately*, as magnetic field lines are *closed* lines ("an infinitely long cylindrical electromagnet has a uniform magnetic field inside, and no magnetic field outside" [1], but in reality
    there is no such thing as "an infinitely long cylindrical electromagnet").

    One of Maxwell's equations (Gauss' Law for Magnetism) is in differential form

    rec ria B = 0,

    which is equivalent to the statement before; because if for any volume as
    much "field" is "flowing out" as is "flowing in" (which is indicated by the field lines, their density, and their direction, then the divergence of the field is zero everywhere:

    re#_V dV (rec ria B) = re>_A dA ria B = 0,

    where in the first identity we have used Gauss' Theorem to describe the
    problem in terms of the amount of "field" that is flowing out perpendicular
    to surface that is enclosing the volume.

    The simplest magnetic field, that of a bar magnet, therefore looks approximately like this (use a fixed-width font to view it):

    _ _
    .'' ''. .'' ''.
    : .''.: :,''. '
    : : .::-::. : :

    : : |::S::| : :
    : : '::-::' : :
    . '--': :'--' . __
    '.._..' '.._..' |PE


    Notice how these field lines are *closed* lines, and only *approximately* parallel within any given volume.

    [1] <https://en.wikipedia.org/wiki/Magnetic_field#Interactions_with_electric_currents>

    there will be equal and opposite forces on these.

    Nonsense.

    To obtain a net force, the magnetic field must be different at the N and S poles.

    It *is* different (it has a different direction at each pole; see above),
    but your conclusion is wrong.

    That is, the field must have a non-zero gradient. (Check dictionary, if necessary)

    Nonsense. The magnetic field is a *vector* field. The gradient operator
    for it is not (simply) defined, and the field does not do any work on a
    charged particle.

    https://en.wikipedia.org/wiki/Magnetic_moment#Force_on_a_moment

    A link to a Wikipedia article is not a sufficient explanation, not even when you are referring to a section of such an article.

    Probably you are referring to

    | F_{loop} = rec(mrau ria Brau)

    This is NOT the "gradient of magnetic field". It is the gradient of _the scalar product of some magnetic moment mrau and the magnetic flux density field Brau.

    The magnetic (flux density) field is a _vector_ field (magnetic field: Hrau = Braureo++reC + Mrau, where Mrau is the magnetization). The gradient is only (simply)
    defined for *scalar* fields (and produces a vector field).

    Moreover, the magnetic field lines are closed, which is what

    rec ria Brau = 0

    means; so it is NOT defined by a gradient field (unlike the electric field: Erau = -rec+a, where +a is the electric potential field), but a _curl_ field: the
    curl of the magnetic vector potential --

    Brau = rec |u Arau

    (because the divergence of a curl field is zero), -- so it does not make
    sense to speak of the gradient of the magnetic field.

    At best, one can speak of the _directional_ gradient of _the strength_ of
    the magnetic (flux density) field (which then is a scalar field); but then
    you have to specify the direction, too.

    For example, the magnetic field around an "infinitely long" cylindrical conductor with radius R through which a uniform current I is flowing is in
    SI units

    Brau(r) = {(++reC/2) (I r/R^2) eraub|-, 0 <= r < R;
    (++reC/2) (I/r) eraub|-, r >= R,

    so

    B(r) = {(++reC/2) (I r/R^2), 0 <= r < R;
    (++reC/2) (I/r), r >= R,

    and

    rec_r B(r) = ree_r B(r) = {(++reC/2) (I/R^2), 0 <= r < R;
    (++reC/2) (-I/r^2), r >= R.

    This shows that in this case the only way to have the strength of the
    magnetic field inside the conductor fall of faster than linearly is to have
    an electric current density that decreases with the distance from the axis
    of the conductor.

    You could say that, *because* it has a (non-zero) magnetic field (not vice-versa). An object is not a magnet /per se/.

    It is pushed by the magnetic fields of the sun and galaxies.

    Not enough.

    That's what makes the earth go round the sun.

    No, that's nonsense. The best explanation that we have for that is _gravitation_. Gravitation is NOT the same as magnetism.

    Terra (Earth) orbits the barycenter of the Sol System because it formed from
    a rotating planetary disk. That disk was rotating because it formed from
    the rotating part of a molecular cloud at the same time as Sol (the Sun) formed; it was what was left over from the star's formation (the star formed because that part of the cloud had cooled enough by emitting radiation, and
    was dense enough so that gravitation caused it to collapse on itself; the collapse caused its density to increase further, and its temperature to increase again, eventually that much that nuclear fusion became possible and likely). That piece was rotating, because small imbalances in mass (perhaps supported by a nearby supernova) cause particles of a molecular cloud to
    move in different directions, and when they become too close, they begin to orbit each other (or rather their common barycenter) due to gravitation.

    This is not just a story or a model anymore because we can observe it in the formation of other stars and their planetary systems.

    [I hope this is just sarcasm, not due to ignorance of basic physics.]

    No. There are other reasons to worry about magnetic pole reversal, for
    example increased exposure to the solar wind during the time that it happens.

    We'll start orbiting the sun in the opposite direction.

    No. Geomagnetic reversals have happened several times already, and there is
    no reason for and no evidence of an associated reversal of orbital velocity.

    <https://en.wikipedia.org/wiki/Geomagnetic_reversal>

    Or maybe it will just make time go backwards. Who knows?

    Neither of these assumed effects is going to happen.

    If you have gotten the idea from one of the first (the first?) Superman
    movie that time would depend on the direction in which Earth is rotating: That's just fantasy.

    Superman might be able to reverse time, but reversing the direction of
    rotation is then a consequence of that, and not the cause. Otherwise this scene is (yet another piece of) evidence of the author's ignorance of basic physics.

    [You can see that Superman is fantasy, and not science-fiction, if you
    consider that Lois Lane is not cut in three pieces when he catches her
    without adapting to her falling speed first, a scene that was hilariously discussed by the friends at the beginning of an episode of "The Big Bang Theory" :-D]

    NASA studies the geomagnetic field (but ISTM that NOAA studies it more), not what you are claiming.

    <https://www.swpc.noaa.gov/>

    Check there website.

    Check it yourself. You will find that you have misunderstood a lot of
    things in this regard:

    <https://science.nasa.gov/sun/solar-storms-and-flares/>

    They also said earth rotates around its axis,

    That is correct.

    not the sun.

    The motion of (the planet) Terra (Earth) around (the star) Sol (the Sun) is simply not *called* "rotation" (except by ignorant people).

    It is called _revolution_ or _orbiting_: the curve that is described by
    Earth in its (translatory) motion around Sol more precisely, the barycenter
    of the Sol System) is called "orbit"; it is approximately an ellipse.

    So *that* was probably meant in a text by NASA that you might have read.

    The Bible is a heavily redacted account of campfire and bedtime stories of ignorant tent-dwelling bronze-age nomads, NOT a textbook. To give you an idea how ignorant they were: they did not even know that Earth is a planet that is orbiting a star, and that the Sun is that star.

    Not only did Joshua not made the Sun to stand still, because he could not; there is also no evidence to support the idea that he ever existed:

    <https://en.wikipedia.org/wiki/Joshua#Current_mainstream_opinion>

    He made all the virgin Amorite girls hold up their mirrors to reflect
    the magnetic field the other way, [...]

    Mirrors do not "reflect magnetic fields". They reflect _light_, which is (best described as) an electromagnetic wave: an oscillation of electric and magnetic fields that _stay in place_ while that happens.

    What a silly claim. Reflector telescopes have mirrors. They can see
    magnetic storms on the sun. You need some schooling.

    Too bad you can't prove anything.


    so the earth stopped spinning while his men finished slaughtering the

    It's you that needs the schooling. Optical telescopes can't see magnetic storms. They can see the optical signal from writhing loops of hot

    the writhing

    Too bad you can't prove anything.

    JFTR: I have studied Physics, including special and general relativity.
    So this is a very ludicrous claim by yet another wannabe/crackpot on the Net.

    More importantly, contrary to what you can read in most popular-scientific texts, spacetime is NOT a "fabric". It is a manifold (a special
    *mathematical* space), a part of a mathematical model and framework, with
    which we assign coordinates to events in order to describe and predict how Nature behaves:

    <https://www.forbes.com/sites/startswithabang/2018/08/11/ask-ethan-is-spacetime-really-a-fabric/>

    And what's your evidence that this discontinuity exists (or ever
    existed). The Old Testament is just a repeatedly copied ancient text.
    The copying process isn't error free.

    In addition to being propagated first by word-of-mouth (oral tradition) and only much later told to scribes, and then copied by scribes from papyrus to parchment and vellum to paper, and translated from Hebrew to Aramaic to
    Koine Greek to Old English etc. (as of today, for example the Bible Gateway
    Web site contains 64 English-speaking versions already [1]), the Bible was
    also heavily and wilfully redacted several times.[2][3]

    This does not have much to do with any of the sciences for which the groups have been set up that this had been crossposted to. But it is important to know especially for (religious) people who think that the Bible (or any
    other religious text) would be a science textbook or a history book (an idea that is even rejected by *biblical* scholars).

    You can post what you like. This is an unmoderated group.
    We don't have to like it, and we can and will ignore you if you don't have anything useful to say.

    Full ACK.

    JFTR: I have studied Physics, including special and general relativity.
    So this is a very ludicrous claim by yet another wannabe/crackpot on the Net.

    Wait, Tom, JFTR. Didn't you say your plonking me? Plonk means you
    don't read my posts or reply to them anymore. It doesn't mean you keep
    up the conversation through 3rd hand replies.

    Yeah, we know, you just had to play your "Im smarter than you" card.
    Reading wikipedia doesn't mean you "studied Physics".

    Also, boasting about "BSc Student at University of Bern" on his ResearchGate page doesn't make him a ohysicist qualified to pronounce on all the stuff
    he pretends to be an expert on.

    If thats so then
    I studied just as much with a GED as you. You really need to study how
    to stop being a horse's ass. And read usenet long enough to read some
    real netiqette, cuz everything you think you know about that is wrong.

    There is a nice video

    "Animation vs. Physics" (2023) - Alan Becker

    where near minute seven, coils placed in space are used to accelerate
    a space ship. While this might not work in reality, it's still nice
    to watch that whole video from start to end (16 minutes).

    I just see there's another video "Animation vs. Math" I have not
    watched yet . . .

    PS: A web page explains that the idea was that "the south pole of
    Orange's ship is facing the north pole of the first magnetic ring"
    and so the ship is accelerated towards the ring. However, the video
    ignores that when leaving the ring, the ship is still attracted to
    the ring, and therefore it would then be accelerated backwards . . .

    What are the effects of magnetic field lines on star formation in galaxies?

    These natural magnetic fields in galaxies and their gradients,
    I think, are relatively weak. Over long timescales and over larger
    spatial regions, their effects can accumulate and become noticeable.
    But to drive a spacecraft, you'd need fields that are fairly strong
    at the location of the ship and at the moment the ship is there.

    It seems those are playing a much bigger role in the forming of galaxies and stars and the 'big bang' in the latest research.

    So that makes me wonder if a spacecraft with just a permanent magnet >>>>> that you can move to give you a force in the direction you want to go >>>>> could be used as a simple fuel-less drive?
    Electromagnets should work too of course.

    Any aliens here that have used it?

    Earth has a magnetic field, and nobody uses magnets to drag boats or
    aircraft around.

    Earth *is* a magnet. It is pushed by the magnetic fields of the sun and >>> galaxies. That's what makes the earth go round the sun.

    Utter nonsense.

    No, it cannot.

    Did you know Joshua commanded the sun to stand still for 2 hours so he
    could finish his slaughter?

    The Bible is a heavily redacted account of campfire and bedtime stories of ignorant tent-dwelling bronze-age nomads, NOT a textbook. To give you an
    idea how ignorant they were: they did not even know that Earth is a planet
    that is orbiting a star, and that the Sun is that star.

    Not only did Joshua not made the Sun to stand still, because he could not; there is also no evidence to support the idea that he ever existed:

    <https://en.wikipedia.org/wiki/Joshua#Current_mainstream_opinion>

    He made all the virgin Amorite girls hold up their mirrors to reflect
    the magnetic field the other way, [...]

    Mirrors do not "reflect magnetic fields". They reflect _light_, which is
    (best described as) an electromagnetic wave: an oscillation of electric and magnetic fields that _stay in place_ while that happens.

    so the earth stopped spinning while his men finished slaughtering the
    rest of the Amorites. Then Josh's men ravished their new concubines.
    They were the sluttiest virgins.

    You are just trolling, right? Otherwise I suggest that you also attend a
    real school, not just Sunday school.

    More importantly, contrary to what you can read in most popular-scientific texts, spacetime is NOT a "fabric". It is a manifold (a special

    And what's your evidence that this discontinuity exists (or ever
    existed). The Old Testament is just a repeatedly copied ancient text.
    The copying process isn't error free.

    In addition to being propagated first by word-of-mouth (oral tradition) and

    only much later told to scribes, and then copied by scribes from papyrus to parchment and vellum to paper, and translated from Hebrew to Aramaic to
    Koine Greek to Old English etc.

    You obviously never read a Old English Bible.


    This does not have much to do with any of the sciences for which the groups have been set up that this had been crossposted to.

    Then you better plonk me again, good buddy. It might take 6 or 8 times.
