Asked by Robert
Two coils, held in fixed positions, have a mutual inductance of 165 µH. What is the peak emf in one coil when the current in the other coil is I(t) = 16.0 sin(1.15 103t), where I is in amperes and t is in seconds?
Just a few hints on how to start it off would be very appreciated, thank you.

The peak emf is the mutual inductance TIMES the maximum rate of change of current in the other coil. That you get from the derivative of the current there.
That max dI/dt is 16*1150 amp/s
