A circular loop of wire of radius 10.0 cm rests on a table. Above the table a magnet moves downward toward the wire at some speed v. The average emf induced in the loop during this time is V. If you wanted to get an average emf of 2V in the wire then which of these changes could you make?   a. quadruple the speed to 4v   b. reduce the area of the circular loop to one-half as much   c. hold the magnet closer to the coil but do not move it   d. quadruple the area of the circular loop   e. double the speed to 2v
