An aluminum ring of radius r₁=5.00 cm and a resistance of 3.05 x 10-42 is placed around one end of a long air-core solenoid with 920 turns per meter
and radius r₂ = 3.00 cm as shown in the figure below. Assume the axial component of the field produced by the solenoid is one-half as strong over the area
of the end of the solenold as at the center of the solenoid. Also 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.
(a) What is the induced current in the ring?
(b) At the center of the ring, what is the magnitude of the magnetic field produced by the induced current in the ring?
UT
(c) At the center of the ring, what is the direction of the magnetic field produced by the induced current in the ring?
