Problem
A small cylindrical sample of aluminum is suspended by a thin fiber between the pole faces of an electromagnet. When the field is switched on, the sample rotates so that its axis aligns with the field and it drifts slightly toward the region of strongest field. As soon as the current in the electromagnet is turned off, the sample returns to its original orientation and shows no residual magnetization.
Which classification of magnetic behavior best matches the observed properties?
(a) Ferromagnetic
(b) Diamagnetic
(c) Paramagnetic
(d) Antiferromagnetic
