Questions
In fig. two long parallel wires carry equal currents
in opposite directions. Point O is situated midway between the wires and the X-Y plane contains the two wires and the positive Z-axis comes normally out of the plane of paper. The magnetic field B at O is non-zero along
detailed solution
Correct option is D
Here, the currents are in opposite directions. The magnetic field adds at O. Thus the net magnetic field is along negative Z-axisTalk to our academic expert!
