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 D? into the plane in the negative y direction in quadrant I in quadrant IV out of the plane in the negative x direction in the positive x direction in quadrant II in quadrant III in the positive y directionExplanation / Answer
7 in the positive x direction
