    Magnetism Photons
AI Thread Summary
Research on the effects of magnetism on photons reveals that while photons themselves are not charged and thus not directly affected by magnetic fields, certain materials can influence the propagation of electromagnetic waves. The discussion highlights phenomena such as the Faraday effect and magneto-optics, which modify the behavior of light in the presence of magnetic fields. Additionally, techniques to bend light around objects, rendering them invisible to specific wavelengths like ultraviolet or microwaves, are mentioned. These methods often involve manipulating electromagnetic waves using engineered materials. Overall, the interplay between magnetism and light presents intriguing possibilities in both theoretical and practical applications.

Im looking to do a little research on the effects of magnetism on photons. Can someone point me in a good direction to start? Any rare phenomena that is worth mentioning concerning this subject? Also, I read a while ago that scientists can bend light around small objects and make them invisible (I believe) either to ultraviolet light or microwaves, how would this be achieved?
 
Physics news on Phys.org
Generally, since a photon has no charge, it is not affected by a magnetic field
there's quite a few links in google when you ask your question there.
even some come back to the physics forum archives where one of our PF mentors Zapperz made some good comments on the subject

mybe he will pop up again in this thread and do some clarifying

cheers
Dave
 
Hopefully he will. Thanks. Anyone else maybe have some help for me?
 
If your question is, "can magnetic fields interact with electromagnetic waves?," then the answer is yes. Certain materials respond to static magnetic fields in such ways to modify the propagation of high-frequency electromagnetic waves such as microwaves and light. These are often used in engineering applications where you want to prevent feedback of EM radiation in your system. Some key words to look into are the Faraday effect, magneto-optics, and ferrites.
 
Thread 'Motional EMF in Faraday disc, co-rotating magnet axial mean flux'
So here is the motional EMF formula. Now I understand the standard Faraday paradox that an axis symmetric field source (like a speaker motor ring magnet) has a magnetic field that is frame invariant under rotation around axis of symmetry. The field is static whether you rotate the magnet or not. So far so good. What puzzles me is this , there is a term average magnetic flux or "azimuthal mean" , this term describes the average magnetic field through the area swept by the rotating Faraday...
It may be shown from the equations of electromagnetism, by James Clerk Maxwell in the 1860’s, that the speed of light in the vacuum of free space is related to electric permittivity (ϵ) and magnetic permeability (μ) by the equation: c=1/√( μ ϵ ) . This value is a constant for the vacuum of free space and is independent of the motion of the observer. It was this fact, in part, that led Albert Einstein to Special Relativity.
