Question

The suspension of a moving coil galvanometer provides a restoring torque of 12 x 10^-6 Nm per degree. Calculate the torque exerted when the coil deflects through 75°. If the coil has effective dimensions 40 mm x 15 mm, wound with 400 turns and the deflection of 45° occurs when a current of 5 mA passes through the coil, calculate the strength of radial field in which the coil lies.​

Answer 1
