A circular coil enclosing an area of 120 cm2 is made of 190 turns of copper wire (shown in the figure below). The wire making up the coil has no resistance; the ends of the wire are connected across a 7.00-9 resistor to form a closed circuit. Initially, a 1.40-T uniform magnetic field points perpendicularly upward through the plane of the coil. The direction of the field then reverses so that the final magnetic field has a magnitude of 1.40 T and points downward through the coil. If the time interval required for the field to reverse directions is 0.500s, what is the average current in the coil during that time?
