A circular coil of n turns and area of crosssection A , carrying a current i, rests with its plane normal to an external magnetic field B. The coil is free to turn about an axis in its plane perpendicular to the field direction. If the moment of inertia of the coil about its axis of rotation is I, its frequency of oscillation about its stable equilibrium is given by
