Consider a rectangular loop of wire ABCD of dimensions a × b (width × length), carrying current I, mounted on a pivot rod (axis of rotation), and placed in a uniform external magnetic field B. Let the plane of the loop make an angle φ with the magnetic field direction, so the normal to the loop m...
