4. Two coils of wire are placed close together. Initially a current of Ip=2.5 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 At = 3.7 x 10-2 s. During this time the average emf induced in the other coil is Es = 1.7 V. What is the mutual inductance M of the two-coil system? system to SD C A qool odio lo lo...

a)During a 82-ms interval, a change in the current in a primary coil occurs. This change leads to the appearance of a 4.2-mA current in a nearby secondary coil. The secondary coil is part of a circuit in which the resistance is 12 Ω. The mutual inductance between the two coils is 3.2 mH. What is the change in the primary current? b) The magnetic flux that passes through one turn of a 13-turn coil of wire changes to 3.78...
