Problem
A magnetic dipole with dipole moment magnitude 0.020JT−1 is released from rest in a uniform magnetic field of magnitude 52mT. Its rotation is unimpeded. When the dipole moment is aligned with the magnetic field, its kinetic energy is 0.80mJ.
(1) What is the initial angle between the dipole moment and the magnetic field?
(2) What is the angle when the dipole is next momentarily at rest?
