Problem
A circular conducting loop with resistance 2.0 Ω lies in a uniform magnetic field directed into the page. The magnetic flux through the loop decreases uniformly from 5.0 mWb to 0 in 0.10 s.
Describe the direction of the induced current in the loop and explain in one or two sentences why the current eventually becomes zero after the flux reaches zero.
