A96-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? (μ0 = 4π × 10-7 t ∙ m/a)
