tcepsaIf a bar magnet is oriented near a current-carrying wire so that the magnet's field lines cross perpendicularly to the direction that the current is flowing, and they are motionless relative to each other, the magnet will experience a net force of zero from the current in the wire.
(feel free to present examples to the contrary--if this statement is incorrect, I'd rather find out sooner than later ;)
[Technically, I think that the net force is still zero even if the magnet is moving relative to the wire as long as its distance from the wire remains constant and the magnetic field lines remain perpendicular to the wire. However, this should not strictly be necessary for this project, so it's more a point of trivia than anything really pertinent]
