Problem
A small pellet of bismuth is placed on a nearly frictionless horizontal surface directly beneath the gap between the north and south poles of a strong permanent magnet. When the magnet is slowly lowered, the pellet slides away from the region of strongest field. When the magnet is removed, the pellet shows no magnetization.
Which classification of magnetic behavior is most consistent with this observation?
(a) Paramagnetic
(b) Diamagnetic
(c) Ferromagnetic
(d) Superparamagnetic
