(Solution) - An aluminum ring of radius 5 00 cm and resistance 3 00 -(2025 Original AI-Free Solution)

Paper Details

An aluminum ring of radius 5.00 cm and resistance 3.00 x 10?4 ? is placed around the top of a long air-core solenoid with 1 000 turns per meter and a smaller radius of 3.00 cm, as in figure. If the current in the solenoid is increasing at a constant rate of 270 A/s, what is the induced current in the ring? Assume that the magnetic field produced by the solenoid over the area at the end of the solenoid is one-half as strong as the field at the center of the solenoid. Assume also that the solenoid produces a negligible field outside its cross-sectionalarea.
