A circular coil enclosing an area of 120 cm is made of 210 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 7.00-0 resistor to form a closed circuit, Initially, a 1.80-T uniform magnetic field points perpendicularly upwardthrough the plane of the coil. The direction of the field then reverses so that the final magnetic field has a magnitude of 1.80 T and points downwardthrough the coil. If the time interval required for the field to reverse directions is 0.400 s, what is the average current in the coil during that time?B
