Three infinitely long wires, each carrying a current 1 A, 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:

Question

Infinity Learn · Accepted Answer

The magnetic field due to wire placed along $$x-axis$$ will be zero. The point under consideration is semi finite position of the wires placed along $$y-axis$$ and $$z-axis$$.Magnetic field due to wire placed along $$y-axis$$,B→$$y=$$μ$$0I4$$$$π$$r  $$k^Magnetic$$ field due to wire placed along $$z-axis$$,B→$$z=$$μ$$I4$$$$π$$r  −$$j^Hence$$, net magnetic field, B→$$=$$μ$$0I2$$$$π$$r  $$k^$$−$$j^After$$ substituting the values, we get,B→$$=$$μ$$08$$π  $$k^$$−$$j^T$$
