Figure 30-47 shows two parallel loops of wire having a common axis, Consequently, 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 the constant rate dx/dt=v, (a) Find an expression for the magnetic flux, through the area of the smaller loop as a function of x, (Hint: See Eq. 29-27.) In the smaller loop, find (b) an expression for the induced emf
