Question:
can a magnet bend light


Replies:
No.

Ok, that's not quite true. A magnetic field contains energy, and energy, through its equivalence to mass, has a gravitational field, which can bend light. But the effect on light of any magnetic field we'll ever see would be so small it's utterly negligible.

Light is electromagnetic radiation consisting of an orthogonal electric field and magnetic field. The cross product of these two fields yield the direction of propogation (E x H = dir. Prop). Therefore, light can be bent in the effect that it's polarization changes. This is the principle that allows those nifty flat LCD screens to work, as well as numerous fiber optic sensors.
