Question

A moving coil galvanometer consists of a coil of n turns and area a, suspended by a thin phosphor bronze strip in radial magnetic field

b. The moment of inertia of the coil about the axis of rotation is l and c is the torsional constant of the phosphor bronze strip. When a current i is passed through the coil, it deflects through an angle (in radians). When a charge q is passed almost instantly through the coil, the angular speed acquired by the coil is

Answer 1
