Assignment:
Two parallel loops of wire having the same common axis. The smaller loop of (raduis r ) and is above the larger loop (raduis R) by a distance X>>R. The magnetic field due to the counterclockwise current i in the larger loop is nearly uniform throughout the smaller loop. Suppose that x is increasing at a constant rate dx/dt = v. (a) find the expression for the magnetic flux through the area of the smaller loop as a function of x. In the smaller loop, find the expression for the induced emf and the direction of the induced current.
