Question

I have a scenario here. There is a loop of resistance of 12 m within which there is a small wire loop enclosed. The larger loop is 0.20 m long and has a radius of 0.045 m and 350 turns of wire. If you wanted the current in the larger loop of wire to match your answer from part 1a, how fast would you need to change the current in the smaller loop of wire? The current in part 1a is 2.57 a
