Magnetic lines of flux

 707_linews of flux.png

A line of flux is a line indicating the direction in which a free north pole would travel, if placed in the field at that point. Alternatively it is the direction in which the north pole of a compass needle would point. The direction which would be taken is indicated on the lines of flux by arrow heads.

Therefore lines of flux emanate from north poles and re-enter at south poles, see diagram below.
