    If light is electrom-magnetic radiation why don't I see it bend and warp around a magnet?

    I'm asking this question. Obviously, because I don't know the answer. If light is made up of electric and magnetic fields, are those fields effected by magnets?

    If I held a powerful magnet in my hand, would the path of the light be effected by the magnets field? Is the light repulsed, or attracted to the magnet? Is there a change in the magnets flux? Is it a case, I'd need a very big magnet to see the effect?

    Scroll down to the bottom of this article and read about Delbruck scattering. The article also mentions that light wouldn't be bent to any measurable level. I'd imagine that because the photon has no charge, that's why it cannot be bent to any appreciable level.
