A solenoid runs though the x-y plane with 3/m x 104 (turns per meter) with current that is always counter-clockwise. Initially, the current is 5 amps for the solenoid. A square wire with sides of 0.49 meters is wrapped 21 times and is placed in the x-y plane within the solenoid. Due to the current changing in the solenoid over a time of 0.30 seconds, the average induced current creates a magnetic moment of 73.7 x 10-3 A m2 in...
