Question:

You have a wire of length L = 1.00 m from which to make the square coil of a dc motor. The current in the coil is I = 1.7 A, and the magnetic field of the motor has a magnitude of B = 0.34 T. Find the maximum torque exerted on the coil when the wire is used to make a single-turn square coil and a two-turn square coil.
