Passage
The figure shows a circular loop of radius a with two long
parallel wires (numbered 1 and 2) all in the plane of the
paper. The distance of each wire from the centre of the loop is
d. The loop and the wires are carrying the same current I. The
current in the loop is in the counter-clockwise direction if
seen from above.
