A circular conducting ring with radius r0=0.0420 m lies in thexy-plane in a region of uniform magnetic field . In thisexpression t0=0.0100 s and is constant t is time is the unitvector in the +z-direction and =0.0800 T is constant. At points aand b (see the figure ) there is a small gap in the ring with wiresleading to an external circuit of resistance R=12.0 . There isno magnetic field at the location of the external circuit.
