Q)
A magnetic field B = $B_{\circ} sin(\omega t)\hat{k}$ covers a large region where a wire AB slides smoothly over two parallel conductors separated by a distance d, as shown in the fig. The wires are in the x - y plane. The wire AB (of length d) has resistance R and the parallel wires have negligible resistance. If AB is moving velocity $\upsilon$, what is the current in the circuit?
