An electric motor consists of a 70 turn coil 3.0 centimeter in diameter, mounted between the poles of a magnet that produces a 0.07 T field.
(a) When a 7.2 Amp current flows in the coil, calculate its magnetic dipole moment?
Answer = _______________ A•m2
(b) Calculate the maximum torque developed by the motor?
Answer = ______________ N•m
