Suppose the loop is moving toward the solenoid (to the right). Will current flow through the loop down the front, up the front, or not at all? Explain in terms of magnetic forces exerted on the charges in the wire of the loop. Describe the direction of the magnetic moment of the loop. Given your answer, do you expect the loop to be attracted toward or repelled from the solenoid?

See explanation

Explanation:

The magnetic force is

F = qvB sin θ

We see that sin θ = 1, since the angle between the velocity and the direction of the field is 90º. Entering the other given quantities yields
