Question

Equation (66) is obviously also applicable to the exterior of any conductor of circular cross section carrying a current I in the az direction in free space. The zero reference is arbitrarily set at p = b. Now consider two conductors, each of 1 cm radius, parallel to the z axis with their axes lying in the x = 0 plane. One conductor whose axis is at (0, 4 cm, z) carries 12 A in the az direction; the other axis is at (0,-4 cm, z) and carries 12 A in the -az direction. Each current has its zero reference for A located 4 cm from its axis. Find the total A field at:

(c) (4cm,4cm,z);

please show steps to the answer

Explanation / Answer

Is there a diagram associated with it because otherwise taking the zero reference for A is not sure. All the other things though are clear except that only.
