a) For a circular coil of 10 turns, radius 0.1 m and a total resistance of 1.0 Ohm, how much current is induced if a magnetic field changes at a rate of 0.5 T/s through it? Assume that the effective area of a maximum and the coil is stationary. Units mA
b) Consider a square loop of wire (sides of 0.25 m) with a resistor included. A bar magnet with the north end up front is approaching the closed loop and thus induces a current. If the resistor has a resistance of 1.5 Ohms, and the rate of change of magnetic field due to the incoming bar magnet is 0.01 T/s, what is the rate of energy dissipation across the resistor?
