Chapter 21, Problem 10P

A circular loop of wire a radius of 12.0 cm is lying flat on a tabletop. A magnetic field of 1.5 T is directed vertically downward through the loop (Figure 21.46) (a) If the loop is removed from the field region in a time interval of 2.0 ms, find the average emf that will be induced in the wire loop during the extraction process. (b) If the loop is viewed looking down on it from above, is the induced current in the loop clockwise or countclockwise?
