Q. A circular coil enclosing an area of 96 cm2 is made of 199 turns of copper wire. The wire making up the coil has resistance of 3.0 , and the ends of the wire are connected to form a closed circuit. Initially, a 1.1 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 1.1 T and points downward through the coil. If the time required for the field to reverse directions is 0.17 s, what average current flows through the coil during that time?
