Two long thin, parallel conductors carrying equal currents in the same direction are fixed parallel to the x-axis, one passing through y = a and the other through `y=-a`. The resultant magnetic field due to the two conductors at any point is B. Which of the following are correct?

Options

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. At all points on the z axis, excluding the origin, B has only a y component
D. B cannot have an x component

Answer

A, B, C, D

Explanation

Field on y axis will be along z axis
