Which of the following types of materials shows a movement from a weaker region to a stronger region of a non-uniform magnetic field?

Correct option is A

Explanation:
 Paramagnetic substances develop feeble magnetization in the direction of the magnetizing field.
 They are weakly attracted by magnetic fields and move from weaker to stronger regions of the magnetic field.
 Their magnetic susceptibility (K) is small and positive (i.e., 0  Examples include manganese, aluminum, chromium, and platinum.
 Hence, they demonstrate the behavior described in the question.
