either doubles or halves (determine which is appropriate for each picture), in the course of 0.300s. The radius of the coil is 1.50 cm, and the resistance is

20.0 02. Determine magnitude and direction of the induced current in both cases.

(b) A plastic cart has a mass of 3.00 kg, and moves with negligible friction on a horizontal surface with a speed of 3.00 m/s. The cart carries a rigid

rectangular loop of wire (mass is negligible), as shown. The resistance of the wire is 500 Ω

1. Find the direction and magnitude of the current when the front edge of the loop is at x = 0.

2. Find the direction and magnitude of the current when the front edge of the loop is at x = 0.10 m.

3. Find the direction and magnitude of the current when the front edge of the loop is at x = 0.30 m.
