An  87 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 resistance is  3.0 ohms. The mutual inductance of the coil and solenoid is 63   At a given instant, the current in the solenoid is 550 mA, and is decreasing at the rate of 2.5 A/s. At the given instant, the induced current in the coil is closest to: 
A) 53 µA 
B) 42 µA 
C) 63 µA
