Electrodynamics
The Motor Effect
Two bar magnets can repel each other.
Since a current carrying conductor becomes a bar magnet, when placed next to a real bar magnet, it can also cause repulsion.
However the direction in which the conductor will feel the repelling force is at right angles to the magnetic field of the bar magnet.
