Question

In Figure, the bar magnet is moved toward the loop. IsVa-- Vb
a. Positive b. negative c. zero d1. A strong electromagnet produces a uniform field of 1.60 T over a cross sectional area of 0.200 m2. A coil having 200 turns and a total resistance of 20.00 W is placed around the electromagnet. The current in the electromagnet is then smoothly decreased until it reaches zero in 20.0 ms. What is the current induced in the coil?

a. 0.160 A b. 0.800 A c. 160 A d.800 A. n/a
