Question

Consider two long parallel wires which are perpendicular to the plane of the paper (i.e., the x-y plane). Both wires carry the same current, I. Wire #1 intersects the plane a distance a above point O and wire #2 intersects the plane a distance a below point O. Point C is equidistant from both wires and is a distance a from point O. What is the direction of the magnetic field at C? in the negative y direction in the positive y direction in quadrant I in the positive x direction in quadrant II into the plane in quadrant IV in quadrant III out of the plane in the negative x direction

Explanation / Answer

7 in the positive x direction
