A 3.0-cm-diameter, 14-turn coil of wire, located at z = 0 in thexy-plane, carries a current of 7.5 A. A 2.0-mm-diameter conductingloop with 2.0× 10^−4 Ω resistance is also in the xy-plane at thecenter of the coil. At t = 0 s, the loop begins to move along thez-axis with a constant speed of 75 m/s.
What is the induced current in the conducting loop at t = 200μs? The diameter of the conducting loop is much smaller than thatof the coil, so you can assume that the magnetic field through theloop is everywhere the on-axis field of the coil.
