A very long, straight wire carries a current of 0.12 A. This wire is tangent to a single-turn, circular wire loop that also carries a current. The directions of the currents are such that the net magnetic eld at the center of the loop is zero. Both wires are insulated and have diameters that can be neglected. How much current is there in the loop? \"COD = n V
