Two and Three Current Carrying Wire

  1. May 11, 2009 #1
    If there are two or three parallel same direction current carrying wire where are two points there magnetic field is zero? Are those two points inside or outside of wires?

    Inside.

    Lets suppose that the current is moving from left to right. Now apply right hand thumb rule in region B. The mafnetic field of 3 would be coming out of the plane but that for 1 and 2 it would be inside the plane. And it would be near B cause the magnetic field of 3 not only has to nullify the magnetic field of 2 but of 1 also. Same goes for in the region B
