Changing the direction of light

[adn]

Hi,

Can a magnet change the direction of light (generally, photon or maybe electromagnetic wave)? _if yes, how? _

A magnetic field can change the direction of light propagtion - if it's in a medium such as plasma. In effect, the index of refraction is changed by the magnetic field.

Magneto-optic materials can change the polarisation of an EM waves, which can - using other polarisation dependant optics (such as a birefringent crystal) change the direction of propagation of an em wave.

Be very careful with the two answers given above. A magnetic field, by itself, has no ability to change the direction of light based on the classical Maxwell Equation. The presence of another material that changes its properties due to a magnetic field has a whole different set of mechanism involved.
