"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.
a. suppose that the radius of the loop were increasing. use lenz' law to explain why there would be an induced current through the wire. indicate the direction of that current.
b. check your answer regarding the direction of the induced current by considering the magnetic force that is exerted on the charge in the wire of the loop. "
