R The figure above shows two parallel loops of wire having a co axis. The smaller loop (radius r) is above the larger loop (rac by a distance x >> R. Consequently, the magnetic field due counterclockwise current i in the larger loop is nearly constai throughout the smaller loop. Suppose that x is increasing at 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 smaller loop as a function of x. PB(x) = %3D (b) Determine the magnitude of the induced emf in the small E(t) = %3D (c) Determine the direction of the current in the small loop. Choose one
