A coil has an area of 100 cm? with 224 turns connected across a 5.00 Q resistor to form a closed circuit as in the figure. Initially, a 2.6 T uniform magnetic field points upward through the plane of the coil. The direction of the field then reverses so that the final magnetic field has a magnitude of 2.6 T and points downward through the coil. If the time interval required for the field to reverse directions is 0.100 s, what is the average current (in units of A) in the coil during that time? R
