Question

If two infinite, parallel, z-directed wires of radius “a” lie at x = b/2, y = 0 for one wire and x = -b/2, y = 0 for the other wire. The wires are separated by a center-to center distance “b” where b >> a and the entire system is in a vacuum.

Find: (10) The magnetic field at a distance “d” where d >> b for a current of I in one wire and -I in the other wire. d is any arbitrary point

(20) The capacitance per unit length between the wires.

(20) The inductance per unit length between the wires.
