1. A flexible circular loop of 10 turns lies in the plane of the paper. The radius of the loop is 0.150 m. The magnetic field is 0.250 T directed into the paper. The area of the loop is reduced to zero in 0.125 s. Determine the magnitude of the average induced emf in the loop at that time.
2. Two parallel wires each carry a current of 5.00 A into the plane of paper. One wire is located at (0.500 m,0). Determine he magnetic field at:
a. (0,0) and (0.750,0)
