Question

As a loop of wire with a resistance of 10 Ω moves in a constant non-uniform magnetic field, it loses kinetic
energy at a uniform rate of 4.0 mJ/s. The induced current in the loop:

Answer 1

Answer:

A loop of wire is placed in a magnetic field of uniform strength 3.0 T that is parallel to the parallel to the normal loop. The radius of the loop begins shrinking at the rate of 0.2 m/s. What is the magnitude of the emf induced in the loop while it is shrinking?

A.38 V B. 0.50 V C. 0.43 V D. 0.61 V

Answer 2

the answer is 0.02 Amperes.
