- A circular coil enclosing an area of 140 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 3.00-N resistor to form a closed circuit. Initially, a 1.20-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 1.20 T and points downward through the coil. If the time interval required for the field to reverse directions is 0.200 s, what is the average current in the coil during that time? RA stationary square coil of area 0.1 m2 is brought over time of 2 s into the magnetic field 8.5 T with its plane perpendicular to the magnetic field. The coil has 1523 turns. Calculate the magnetic flux linkage through the coil. Give your answer in SI units.
