Assume a large flat loop with a radius of 10 cm and a small loop with a radius of 1 cm at the center and in the plane of the large loop. What is their mutual inductance in Henry? If the current varies at a rate of 50 Amp/sec in one loop, what will be the electromotive force induced in the other loop?

(a) If an inductor carrying a 1.95 A current stores an energy of 0.250 mJ, what is its inductance? Answer in mH (b) How much energy does the same inductor store if it carries a 3.1 A current? Answer in mJ

A circuit consists of a 20 nF capacitor in series with a 20 µH inductor. If a charge of 30 nC is put on the capacitor, there is an oscillation. (a) What is the maximum current that moves through the circuit? (b) Find the maximum energy in the inductor and the in the capacitor? (c) What is the angular frequency of oscillation? What is the period? (d) Assume the trace resistance in the circuit is 0.102. Describe quantitatively and qualitatively the oscillation in the circuit.

Coil A is a large 300 turn circular coil of radius 77 cm. Circular coil B has 390 turns, a radius of 5 cm and is located L=99 cm from coil A along the same axis. The planes of the two coils are parallel. A) Find the approximate mutual inductance of this pair of coils.     for my answer I got 3.527E-10 H which was wrong B) If the current in coil A varies with time according to I=3t3−8t2−1, where I is in amps and t is in s, find the magnitude of the EMF induced in coil B at time t=2 s.

Two coils are at fixed locations. When coil 1 has no current and the current in coil 2 increases at the rate 18.1 A/s, the emf in coil 1 is 25.6 mV. (a) What is their mutual inductance? (b) When coil 2 has no current and coil 1 has a current of 6.10 A, what is the flux linkage in coil 2?
