A circular coil enclosing an area of 120 cm² is made of 190 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 9.00- resistor to form a closed circuit. Initially, a 1.60-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 1.60 T and points downward through the coil. If the time interval required for the field to reverse directions is 0.500 s, what is the average current in the coil during that time? A

A v-shaped metal rod completes a circuit while sliding without friction on a pair of rails in a uniform magnetic field. The rod is placed symmetrically between the rails, i.e. its vertex is right in the middle between the rails. The angle between the arms of the "v" is 132.45 degrees. B is uniform sliding v-shaped rod The mass of the rod is 382g. The resistor has a value of 2.09 ohm. The magnetic field has a strength of 6.40T and the distance between the rails is 1.25m.

The resistance of the wire is 4.7 ohms and the large loop has a side length of 19 cm, while the smaller loop is half that size.
