CALC A circular loop of wire with radius r = 0.0250 m and resistance R = 0.390 Ω is in a region of spatially uniform magnetic field, as shown in Fig. E29.23. 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) = (0.380 T/s³)t³. What is the current in the loop (magnitude and direction) at the instant when B = 1.33 T?
