Multiple choice

Two infinitely long wires carrying current are as shown in the figure below. One wire is in the y-z plane and parallel to the y−axis. The other wire is in the x-y plane and parallel to the x−axis. Which components of the resulting magnetic field are non-zero at the origin?

  1. x, y, z components

  2. x, y components

  3. y, z components

  4. x, z components

D Correct answer
Explanation

Due to 1A current wire in $x-y$ plane, magnetic field be at origin will be in $x$ direction.

Due to 1A current wire in $y-z$ plane, magnetic field be at origin will be in $z$ direction.

Thus $x$ and $z$ component is non-zero at origin
