6. Induced Currents in Adjustable Loops A copper wire loop is constructed so that its radius. r. can change. It is held near a solenoid that has a constant current through it. Suppose that the radius of the loop were increasing. 3. Use Lenz' law to explain why there would be an induced current through the wire. b. Determine the direction of the induced current in two ways. In each case, explain your reasoning: i. using Lenz' law ii. considering the magnetic force that is exerted on the charge in the wire of the loop (1. Determine the direction of the magnetic moment of the loop. Explain. d. Determine the direction of the force exerted on the loop by the solenoid. Explain
