Field of a Magnet & Magnet in a Uniform Field

A magnetic dipole of magnetic moment $M$ , is freely suspended in a magnetic field of induction B. The minimum and maximum values of potential energy of the dipole, respectively are

Show answer and solution

Answer: (a)

$U = -MB\cos\theta$
Minimum at $\theta = 0^\circ$ : $U = -MB$ ; maximum at $\theta = 180^\circ$ : $U = +MB$ .
So the answer is (a) $-MB, +MB$ .
