Q11) A circular loop of wire with radius r= 0.0480m and resistance R = 0.160 Ģ is in a region of spatially uniform magnetic field, as shown in the figure. The magnetic field is directed out of the plane of the figure. The magnetic field has an initial value of 8.00 T and is decreasing dB/dt = -0.680 T. a) Is the induced current in the loop clockwise or counterclockwise? b) What is the rate at which electrical energy is being dissipated by the resistance of the loop?
a) counterclockwise 0.0308 A
b) 1.51 x 10^-4 W
