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 Point G is equidistant from both wires and is a distance a from point O. The direction of the magnetic field at G is 1. in the negative x direction. 2. into the plane. 3. in quadrant II. 4. in quadrant I. 5. in quadrant IV. 6. in the positive x direction. 7. in the positive y direction. 8. in the negative y direction. 9. out of the plane. 10. in quadrant III. The direction of the magnetic field at D is 1. out of the plane. 2. in quadrant III. 3. in the negative x direction. 4. in the negative y direction. 5. in quadrant IV. 6. in the positive y direction. 7. in quadrant II. 8. in the positive s direction. 9. into the plane. 10. in quadrant I.Explanation / Answer
The feld at C is...
Choices 8 and 10
In the 3rd quadrant pointing in the negative y direction
The field at D is...
Choices 2 and 3
In the 3rd quadrant pointing in the negative x direction
