I am offering  the simple experiment which will answer all questions. It can be executed, using a powerful magnet similar the LHC magnet, here, on the Earth. Except of a magnet, two lasers: blue and red are necessary. Their beams are parallel and directed at one target. They pass between poles of a magnet. The distances between red and blue points on a target and their coordinates on a target at the switched OFF magnet is measured. The same is carried out at the magnet switched ON. Certainly, lasers should be closer to a magnet, and the target is   far as it possible.  

An   expected  result: the red beam, as against a blue beam, will be deflected by a magnetic field.
