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 ?
                                           
  • 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 point of the z-axis, excluding the origin, B has only a y-component.
  • d)
    B cannot have an x-component.
Correct answer is option 'A,B,C'. Can you explain this answer?

On x-axis
A.  B=(μ0I/2πa)- (μ0I/2πa)=0
B.  On y axis say at (y, 0, 0)
B=[-μ0I/2π(a+y)]k + [μ0I/2π(a-y)]k
So except at origin, B has only z-components.
B cannot have x-component as B is perpendicular to direction of I.
