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 102 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?
