Two coils are wound around the same cylindrical form, When the current in the first coils is decreasing at a rate of -0.242 A/s , the induced emf int he second coil has magnituden1.65x10^-3V.
a) What is the mutual inductance of the pair of coils?
b) If the second coils has 25 turns, what is the flux through each turn when the current in the first coil equals 1.20A?
c) If the current in the second coil increases at a rate of 0.360 A/s, what is the magnitude of the induced emf in the forst coil?
