You have a wire of length L = 2.4 m for making a square coil of a dc motor. The current in the coil is I = 0.8 A, and the magnetic field of the motor has a magnitude of B = 0.44 T. Find the maximum torque exerted on the coil when the wire is used to make
(a) a single-turn square coil and
(b) a two-turn square coil.
