A permanent magnet motor has an armature that contains 100loops. The armature is circular with a radius of 250cm. The motor draws a 10 A of current to produce 20 N-m oftorque. What is the strength of the magnetic field producedby the permanent magnet? If the current was reduced to 5 A,how much torque would the motor produce?
