A solenoid is constructed from a 20 cm long iron pipe. A copper wire of thickness 0.6 mm is wrapped tightly around the tube (assume there is no gap between the different coils).
A) What is the magnetic field inside the solenoid if the wires carry a current of 50 A?
B) A circular 8-turn loop of radius 4 cm is placed into the solenoid. What current is needed so that the loop experiences a maximum torque of 0.5 N*m?
C) What orientation should the loop be inside the solenoid in order to experience this torque?
