A coil has an area of 100 cm² with 219 turns connected across a 5.00 2 resistor to form a closed circuit as in the figure. Initialy, a 1.6 T uniform magnetic field points upward through the plane of the coil. The direction of the field then reverses so that the final magnetic field has a magnitude of 1.6 T and points downward through the coil. If the time interval required for the field to reverse directions is 0.100 s, what is the average current (in units of A) in the coil during that time?

Review. Figure P31.31 shows a bar of mass m that can slide without friction on a pair of rails separated by a distance and located on an inclined plane that makes an angle with respect to the ground. The resistance of the resistor is R. and a uniform magnetic field of magnitude H is directed downward, perpendicular to the ground, over the entire region through which the bar moves. With what constant speed v does the bar slide along the rails?
A circular coil enclosing an area of 100 cm2 is made of 200 turns of copper wire (Figure P30.31). The wire making up the coil has no resistance; the ends of the wire are connected across a 5.00- resistor to form a closed circuit. Initially, a 1.10-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 1.10 T and points downward through the coil. If the time interval required for the field to reverse directions is 0.100 s, what is the average current in the coil during that interval? Figure P30.31
