  • This formulation, given by Hannes Alfven inis valid in vacuum. Backus, Astrophysical Journal, vol 23, p, ADS link.


    Consider for instance an electric dipole. I also think the charge distribution considerations are too limited. For intuitively I expect polarization to show up, but not free charges. An infinite cylinder, neutral charge, M constant. So yes, a rotating ring will have non-zero electric field in it.

    Also, intuitively, before the infinite sinning, the ring will have electric field outside it as well. EDIT yet again Xpinning need to think about it, but this can probably be made rigorous as such: In the infinite cylinder case, it should be possible to see how M in one frame changes to M and P in another frame.

    There may be a simple way to use the symmetry of relativity to explain how these mix. I understand the skepticism and the "source" problem, but a spinning magnet is like a collection of separate magnets spinning around in physics perpendicular to their lengths. Amazing this is not settled physics. It may mean we should reassess the sourcing equations.

    It would seem that this problem could be re-expressed in a manner that makes the form of the answer intuitively clear. Consider a cylinder oriented vertically. Its top magnet surface is coated with a thin layer magnrt "North" magnetic monopoles. Its bottom surface is similarly coated with "South" magnetic monopoles.

    The spinning of the cylinder along its vertical axis creates rings of magnetic current due to the resulting circular paths traced out by the magnetic monopoles. These magnetic currents appear in the Maxwell equation corresponding to Faraday's Law in a manner exactly analogous to the appearance of electric currents in the Maxwell equation corresponding to Ampere's Law.

    The rings of magnetic spinning will produce toroidal electric fields concentrated at the ends of the cylinder.

    Nuclear Magnetic Moments. Associated with each nuclear spin is a magnetic moment which is associated with the angular momentum of the nucleus. It is common practice to express these magnetic moments in terms of the nuclear spin in a manner parallel to the treatment of the magnetic moments of electron spin and electron orbital angular momentum.. For the electron spin and orbital cases, the. Jan 20,  · So through these 27 jaw dropping gifs that display something that sounds complicated from the world of physics, we hope to make you appreciate the Estimated Reading Time: 3 mins. The spinning of the cylinder along its vertical axis creates rings of magnetic current due to the resulting circular paths traced out by the magnetic monopoles. These magnetic currents appear in the Maxwell equation corresponding to Faraday's Law in a manner exactly analogous to the appearance of electric currents in the Maxwell equation.

    These fields are analogous to the toroidal magnetic fields produced by rings of electric current. The validity of this answer that E is not zero, but a toroidal configuration at both ends depends on whether a magnetic dipole formed from the aforementioned distribution of magnetic monopoles is equivalent to your cylindrical magnet.

    Interestingly, although magnetic monopoles could be used to create a magnetic field identical to that of your magnetic spinnign field result from electric charges circulating about nucleithe situations are not equivalent.

    There are only two ways to generate an electric field -- electric charges or magnetic currents. Spinning the magnet does not spontaneously generate electric charge. Nor, in the absence of mononoples, does it create a magnetic current. By the way, Gauss' Law does not imply that the electric field is zero. It only implies that the integral of the electric field on a surface enclosing the cylinder is zero.

    The Earth is rotating and has a permanent Magnetic field. It does not exhibits a correspondent Electric field.

    The answer is 0. The magnetic field is due to the presence of a relative motion between the charges inside the Earth electric dipole and the observer.

    Thus, it is a derived quantity much like the Coriolis force. Instead of saying magnetic field I think more appropriate to say magnetic force.

    Physics of MRI. Physics of MRI - Detailed. Magnetism is a property of matter that is a result of the orbiting electrons in atoms. The orbiting electrons cause the atoms to have a magnetic moment associated with an intrinsic angular momentum called spin. Spin will be discussed in more detail a . Nuclear Magnetic Moments.
