Two coils of wire are placed close together. Initially, a current of 3.80 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 1.46 x 10-2 s.
During this time, the average emf induced in the other coil is 2.86 V. What is the mutual inductance of the two-coil system?

During a 58-ms interval, a change in the current in a primary coil occurs. This change leads to the appearance of a 5.5-mA current in a
nearby secondary coil. The secondary coil is part of a circuit in which the resistance is
12 02. The mutual inductance between the two coils is 3.2 mH. What is the change in the primary current?

A long, fine wire is wound into a coil with inductance 5 mH. The coil is connected across the terminals of a battery, and the current is measured a few seconds after the connection is made. The wire is unwound and wound again into a different coil with L = 10 mH. This second coil is connected across the same battery, and the current is measured in the same way. Compared with the current in the first coil, is the current in the second coil
