6- chapter31-question20 An aluminium ring of radius 5.00 cm and resistance 3.00 x 10-n is placed on top cm- of a long air-core solenoid with 1000 turns per meter and radius 3.00 cm, as shown in Figure. Over the area of the end of the solenoid, assume that the axial component of the field produced by the solenoid is half as strong as at the center of the solenoid. Assume the solenoid produces negligible field outside its cross- sectional area. The current in the solenoid is increasing at a rate of 270 A/s. What is the induced current (in A) in the ring?
