29.22     A circular loop of wire with radius r = 0.0480 m and resistance R = 0.160 Ohms is in a region of spatially uniform magnetic field, as shown in Fig. E29.22.  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 at a rate of dB/dt = −0.680 T/s.

(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?

The applied uniform magnetic field is directed out of the page and until no change in magnetic field that enclosed with the circular loop, there is no produced any induced emf in the loop As the field decreases with respect to time the emf is induced in the loop and this emf produces its own magnetic field which opposes the any change in the applied magnetic field. The decreasing applied field is qualitatively means into the page and the induced magnetic field opposite to the decreasing field that is directed out of the page and from right hand rule the direction of the induced current in the loop is counter clock wise direction
