Can a magnetic field in a vacuum bend the path of light?
Can a Magnetic Field Bend Light?
Click For Summary
SUMMARY
A magnetic field in a vacuum does not bend the path of light, as photons are neutral and unaffected by magnetic fields. Magnetic fields can influence the motion of charged particles, induce magnetization in matter, and generate electric fields through changing magnetic fields, as described by Faraday's law. In contrast, gravitational fields can bend light by curving spacetime, but outside of these fields, light travels in a straight line.
PREREQUISITES- Understanding of electromagnetic theory
- Familiarity with the properties of photons
- Knowledge of Faraday's law of electromagnetic induction
- Basic concepts of general relativity and spacetime curvature
- Study the principles of electromagnetic theory in detail
- Explore the behavior of photons in various fields
- Investigate Faraday's law and its applications in electromagnetism
- Learn about general relativity and its implications for light propagation
Physicists, students of electromagnetism, and anyone interested in the interactions between light and electromagnetic fields.

No. As far as I know, magnetic fields can:
1 - affect the motion of free charged particles (photons don't carry charge and are unaffected by B-fields)
2 - cause matter to become magnetized (a net alignment of the dipoles, which are throughout matter)
3 - changing magnetic fields can induce an electric field (see Faraday's law)
These statements are not the most general, but I think they are among the most common points one can make about magnetic fields.

Gravitational field can, as it alters spacetime by introducing curvature. Outside gravitational fields spacetime is flat and thus light follows a straight line path. Fair enough?
