A Loop of Radius R = 3 Cm Is Placed

Multiple Choice

A loop of radius r = 3 cm is placed parallel to the xy-plane in a uniform magnetic field = ( 0.75 T) . The resistance of the loop is R = 18 Ω. Starting at t = 0, the magnitude of the field decreases uniformly to B = 0 in 0.15 seconds. What is the magnitude of the electric current produced in the loop during that time?

A) 0.8 mA
B) 3.9 mA
C) 1.7 mA
D) 2.1 mA
E) 0.2 mA
