The figure above shows two parallel loops of wire having a common
axis. The smaller loop (radius r) is above the larger loop (radius R)
by a distance x >> R. Consequently, the magnetic field due to the
counterclockwise current i in the larger loop is nearly constant
throughout the smaller loop. Suppose that x is increasing at the
constant rate dx/dt = V.
NOTE: Express your answers to parts (a) and (b) in terms of the given variables.
(a) Find an expression for the magnetic flux through the area of the
smaller loop as a function of x.
ÞB(x) =
(b) Determine the magnitude of the induced emf in the smaller loop.
