Figure 30-47 Problem 58.
A square wire loop 20 cm on a side, with resistance20 m , has its plane normal to a uniform magnetic field of magnitudeB = 2.0 T. If you pull two opposite sides of the loop awayfrom each other, the other two sides automatically draw towardeach other, reducing the area enclosed by the loop. If the area is reducedto zero in time t = 0.20 s, what are (a) the average emf and(b) the average current induced in the loop during t?
