Problem 7.2 Cousider a conducting circular loop in a uniform magnetic field By directed into-the-page, as shown above. The loop's radius increases with time as r(t) = at while the loop maintains a constant resistance K. a) Use Lenz's law to find the direction of current flow. b) At time , over a short time interval At, find |A|. c) Use Faraday's flux rule to find the resulting magnitude and direction of current flow. 7-1
