Magnets vibrating near a current?

In school yesterday I was doing a practical and when I moved a small 1.5T block magnet near a rheostat the magnet started vibrating, why does it do this?

If you have a current, then that current will always generate a magnetic field. The formula for how big the magnetic field would be is given by Ampere's Law. So basically, you can treat the current as if it were a magnet too. So your original block magnet started to vibrate because it felt a force of magnetic attraction to or repulsion from your current.
