Two coils are wound around the same cylindrical form. When the current in the first coil is decreasing at a rate of -0.242 A/s, the induced emf in the second coil has magnitude 1.65 x 10-3 V and the mutual inductance of the two coils is 6.82 mH. If the current in the first coil becomes constant, what happens to the mutual inductance?

The current through a coil as a function of time is represented by the equation I(t) = Ae−bt sin(ωt), where A = 5.25 A, b = 1.75 ✕ 10−2 s−1, and ω = 375 rad/s. At t = 0.880 s, this changing current induces an emf in a second coil that is close by. If the mutual inductance between the two coils is 4.35 mH, determine the induced emf. (Assume we are using a consistent sign convention for both coils....

During a 72-ms interval, a change in the current in a primary coil occurs. This change leads to the appearance of a 6.1-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?
