Rotating Bar : Induced EMF|| Torque on a Rotating bar || Examples on rotating bar in magnetic field

Find expression for work done in rotating a bar magnet in a uniform magnetic field.

A square coil of 100 turns and side length 1 cm is rotating in a uniform magnetic field such that axis of rotation is perpendicular to magnetic field. If coil completes 1 rotation in 1ms.Find average EMF induced in muV) in half rotation. ( Magnetic field ( B) = 10^(-5) T ) .
