An electric motor makes use of the torque on a current loop in a magnetic field, to do work. Suppose a washing machine motor has a square coil with N = 100 turns of wire carrying current I in a magnetic field B. Calculate the maximum torque, which occurs when the plane of the coil is parallel to the field vectors. DATA: I= 5.100 A; B = 0.55 T; dimensions = 8.0 cm by 8.0 cm
