Question

Two coils of wire are placed close together. Initially, a current of 2.01 A exists in one of the coils, but there is no current in the other.
The current is then switched off in a time of 2.58 x 102 s. During this time, the average emf induced in the other coil is 3.65 V. What is
the mutual inductance of the two-coil system?

Coil A is a large 1000 turn circular coil of radius 68.0 cm. Circular coil B has 200 turns, a radius of 3.0 cm and is located L = 56.0 cm from coil A along the same axis. The planes of the two coils are parallel. Find approximately the mutual inductance of this pair of coils. *Note* As coil A is much larger than coil B, the B field due to A in the region of B is fairly constant. Use this approximation and proceed.
In the circuit shown in the Figure with 3.0 mH for the inductance and 6.0 uF for the capacitance, S1 has been closed for a long enough time so that the current reads a steady 3.50 A. Suddenly, S2 is closed and S1 is opened at the same instant. What is the maximum charge that the capacitor will receive? What is the current in the inductor at this time? At an instant when the charge on the capacitor is 0.1 mC, what is the current in the inductor? At an instant when the charge on the capacitor is 0.1 mC, what is the rate at which the current in the inductor is changing?
