A circular loop of wire with a radius of 0.0240 m and a resistance of 0.380 Ω is in a region of spatially uniform magnetic field, as shown in 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) = (0.390 T/s^3) t^3.
A) What is the current in the loop (magnitude) at the instant when B = 1.50 T?
B) What is the direction of the current in the loop?
- counterclockwise
- clockwise
