1. 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. & Use Lena's law to explain why there would be an induced current through the wire. would be a sa which means there the I wire b. Determine the direction of the induced current in two ways. In each case, explain your reasoning: using Lenz's law considering the magnetic force that is exerted on the charge in the wire of the loop c. 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. 2. A copper wire loop is initially at rest in a uniform magnetic field. Between times t-t and + Ar the loop is rotated about a vertical axis as shown. Will current flow through the wire of the loop during this time interval? If so, indicate the direction of the induced current and explain your reasoning. If not, explain why not. 1-1, M Axis of rotation 1-1, + Ar 444
