Magnetism & Photons: Research, Rare Phenomena & Invisibility

[Rorkster2]

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?

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

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.

Sure, I can provide some information and suggestions for your research on the effects of magnetism on photons. First of all, magnetism and photons are both fundamental concepts in physics, and their interaction has been studied extensively. One of the main ways in which magnetism affects photons is through the phenomenon of Faraday rotation, where the plane of polarization of a light beam is rotated when passing through a magnetic field. This effect is used in many practical applications, such as in optical isolators and magneto-optic modulators.

In terms of rare phenomena, there are a few interesting examples of magnetism and photons interacting in unique ways. For instance, researchers have recently discovered a new type of magnetism called "topological magnetism," which involves the formation of exotic magnetic structures that can trap and manipulate photons. This could have potential applications in the development of new types of optical devices.

Another rare phenomenon to consider is the quantum Hall effect, which occurs when a strong magnetic field is applied to a two-dimensional electron gas. This results in the quantization of the Hall resistance, and has implications for the behavior of photons in such systems.

Regarding your question about invisibility, yes, scientists have been able to create materials that can bend light around objects, making them "invisible" to certain wavelengths of light. This is achieved through the use of metamaterials, which are artificially engineered structures with unique optical properties. By manipulating the refractive index of these materials, scientists have been able to create a cloaking effect that can hide objects from certain types of electromagnetic radiation.

I would suggest starting your research by looking into these concepts and phenomena and exploring the current literature on the topic. You can also look into specific experiments and studies that have been conducted in this area to get a deeper understanding of the effects of magnetism on photons. Additionally, reaching out to researchers in this field or attending conferences and seminars on the topic can also be helpful in gaining more insight and knowledge. Good luck with your research!
