A circular coil enclosing an area of 100 cm squared is made of 200 turns of copper wire . The wire making up the coil has resistance of 5.0 ohms and the ends of the wire are connected to a form closed circuit . Initially , a 1.1 T uniform magnetic field points perpendicularly upward through the place of the coil . If the time required for the field to reverse directions is 0.10 s , what average current flows through the coil during that time ?
