Question

5) A solenoid with 2 x 106 turns per meter runs through the x-y plane. It initially has a current of 7 amps running clockwise. A wire shaped like a equilateral triangle would 10 times with sides of length 2 meters is placed in the x-y plane in the solenoid. Over a a time of 0.7 seconds, the solenoid changes its current somehow which induces a (average) current in the triangle of 16 amps running counter-clockwise. If the resistance of the triangle is 50 Ohms, what is the final current of the solenoid in amps? solenoid

Answer 1

hope this helps.
