An elastic conducting material is stretched into a circular loop of 12.6 cm radius. It is placed with its plane perpendicular to a uniform 1.17 T magnetic field.

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 R

A single loop of copper wire, lying flat in a plane, has an area of 8.60 cm² and a resistance of 1.50 2. A uniform magnetic field points perpendicular to the plane of the loop.

A rectangular coil of 20 turns of wire measuring 10in on one side and 6in on the other is placed with its plane parallel to the flux in a uniform magnetic field of 400 lines/in^2.
