Two coils are wound around the same cylindrical form. When the current in the first coil is decreasing at a rate of -0.245 A/s , the induced emf in the second coil has a magnitude of 1.70×10?3 V .

Part A

What is the mutual inductance of the pair of coils?

Part B

If the second coil has 29 turns, what is the flux through each turn when the current in the first coil equals 1.15 A ?

Part C

If the current in the second coil increases at a rate of 0.365 A/s , what is the magnitude of the induced emf in the first coil?
