Can a Magnetic Field Affect the Path of a Photon?

Electrons have spin 1/2 and interact with a magnetic field. Since photons have spin 1, I suppose they also feels a force on a magnetic field. So that means that light can be deviated from its original path by a magnetic field?

The important property is not spin angular momentum, but magnetic moment.

Do photons have magnetic moment?

Nope. No charge, dipole, or magnetic moment.
