Four long wires are perpendicular to the x-y plane. Each wire carries the same m

Question

Four long wires are perpendicular to the x-y plane. Each wire carries the same magnitude current. Wire 1 goes through point (a, a, 0) on the x-y plane, wire 2 goes through the point (-a, a. 0), wire 3 goes through the point (-a, -a, 0), and wire 4 goes through the point (a. -a, 0). Wires 1 and 2 carry their currents in the positive z direction and wires 3 and 4 carry their currents in the -z direction. What is the direction of the resulting magnetic field at the origin? the -x direction the -y direction the +x direction There is no direction since the field is zero at this position.

Explanation / Answer

Ans: There is no direction since the feild is zero at this position.

All wire carry same magnitude of current ,so magnitude of magnetic feild created by them are all equal.

Magnetic feild direction can be determined by Flemming right hand rule.

Due to symmetry of the problem magnetic feild direction will be such that net feild will be zero.
