Three infinitely long thin wires
Three infinitely long thin wires, each carrying current i in the same direction, are in the x−y plane of a gravity free space . The central wire is along the y−axis while the other two are along x=±d. (i) Find the locus of the points for which the magnetic field B is zero. (ii) If the central wire is displaced along the Z−direction by a small amount and released,
