A solenoid inductor (self-inductance of 96 mH) is 0.80 m in length and 0.10 m in diameter. A coil is tightly wound around the solenoid at its center (approximately same diameter). The coil's resistance is 6.0 ohms. The mutual inductance between the coil and solenoid is 31 μH. At a given instant, the current in the solenoid is 540 mA and is decreasing at the rate of 2.5 A/s. At this given instant, what is the magnitude of the induced current in the coil?
