Three infinitely long wires, each carrying a current 1A, are placed such that one end of each wire is at the origin, and, one of these wires is along x-axis, the other along y-axis and the third along z-axis. Magnetic induction at point (-2 m, 0, 0) due to the system of these wires can be expressed as

Three long wires, each carrying current i are placed as shown. The middle wire is along Y -axis. The locus of point on the X -axis where magnetic field is zero is

Three semi - inifinte wires, each carrying a current of 1 A are placed on each of the coordinate axes with their ends at the origin, as shown in the figure. The magnetic induction at point P(-2m, 0,0) is

Three infinitely long thin wires, each carrying current i in the same dieretion, are the xy 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, show that it will execute simple harmonic motion. If the linear mass density of the wires is lamda , find the frequency of oscillation.
