A 96-mH solenoid inductor is wound on a form 0.80 m in length and 0.10 m in diameter. A coil is tightly wound around the solenoid at its center. The coil's resistance is 9.9 ohms. The mutual inductance of 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 the given instant, what is the magnitude of the induced current in the coil? (µ_0 = 4Tt × 10^-7 T • m/A) * Q
