A circular coil has moment of inertia
around any diameter and is carrying current to produce a magnetic moment of
. The coil is kept initially in a vertical position and it can rotate freely around a horizontal diameter. When a uniform magnetic field of
is applied along the vertical, it starts rotating, around its horizontal diameter. The angular speed the coil acquires after rotating by
will be
