Coil 14.0 N Solenoid 60.0 V An 819-turn wire coil of resistance 20.5 N is placed above a 11611-turn, 6.36-cm-long solenoid, as shown. Both coil and solenoid have radii of 0.436 cm. a. How long does it take the solenoid current to reach 0.613 times its maximum value? ms b. Determine the average back emf caused by the self-inductance of the solenoid during this interval. Epack = The magnetic field produced by the solenoid at the location of the coil is one-half as strong as the field at the centre of the solenoid. c. The average rate of change in magnetic flux through each turn of the coil during the stated interval is mv. d. Find the magnitude of the average induced current in the coil. Icoil = mA
