Consider a 50-turn circular loop with a radius of 1.75 cm in a 0.25-T magnetic field. This coil is going to be used in a galvanometer that reads 65 for a full-scale deflection. Such devices use spiral springs which obey an angular form of Hooke's law, where the restoring torque is Here x is the torque constant and ? is the angular displacement, in radians, of the spiral spring from equilibrium, where the magnetic field and the normal to the loop are parallel ? 50%
Part (a) Calculate the maximum torque, in newton meters, on the loop when the full-scale current flows in it
Part (b) What is the torque constant of the spring, in newton meters per radian, that must be used in this device?
