A circular loop of wire with radius 0.0270 m and resistance 0.320 Ω
A circular loop of wire with radius 0.0270 m and resistance 0.320 Ω is in a region of spatially uniform magnetic field, as shown in the following figure(Figure 1). The magnetic field is directed into the plane of the figure. At t = 0, B = 0. The magnetic field then begins increasing, with B(t) =( 0.400 T/s3)t3 .
Part A
What is the current in the loop (magnitude) at the instant when B = 1.38 T?
Part B
What is the direction of the current in the loop?
