Problem 22.26 (Multistep)
In the figure below a very small circular metal ring of radius
r= 0.5 cm and resistance x= 5 Ω is at the center of a large
concentric circular metal ring of radius R= 50 cm. The two rings
lie in the same plane. At t= 3 s, the large ring carries a
clockwise current of 5 A. At t= 3.3 s, the large ring
carries a counterclockwise current of 8 A.
