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 = 0.640 s, this changing current induces an emf in a second coil that is close by. If the mutual inductance between the two coils is 4.34 mH, determine the induced emf. (Assume we are using a consistent sign convention for both coils....
