A circular coil enclosing an area of 100 cm^2 is made of 200 turns of copper wire. The wire making up the coil has a resistance of 5.0 ohms, and the ends of the wire are connected to form a closed loop. Initially, a 1.1 Tesla 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 Tesla and points downward through the coil. If the time required for the field to reverse directions is 0.10 seconds, what is the average current that flows through the coil during this time?
The solution determines what the average current the flows through the coil during a given time is.
