Two long thin, parallel conductors carrying equal current in the same direction are fixed parallel to the x-axis one passing through magnetic field due to the two conductors at any point is `B` Which of the following are correct ?(A) B=0 for all points on the x-axis (B) At all points on the y-axis, excluding the origin, B has only a zcomponent. (C) At all points on the z-axis, excluding the origin, B has only an x-component.

A

`B = 0` for all points on the x-axis

B

At all points on the y-axis. Excluding the origin, B has only a z- component.

C
