A conducting rod spans a gap of length L = 0.065 m and acts as the fourth side of a rectangular conducting loop, as shown in the figure. A constant magnetic field with magnitude B = 0.75 T pointing into the paper is in the region. The rod is pulled to the right by an external force, and moves with constant speed v = 0.015 m/s. The resistance in the wire is R = 180Ω. Part (a) Express the magnitude of the magnetic flux going through the loop, Φ, in terms of B, a and L. Part (b) Express the change in the magnetic flux, ΔΦ, in terms of B, L, v and Δt. Part (c) Express the magnitude of the average emf induced in the loop, ε, in terms of B, L, v. Part (d) Calculate the emf, in volts. Part (e) Express the current induced in the loop, I, in terms of ε and R.
