ield magnet poles, we assume that the majority of thelines will go straight from pole to pole, Fig. 22. If nowa circular core is inserted, their course will be so alteredthat each line takes the path of least resistance—that is,runs as long as possible in iron, and only leaps across the 86 ELECTRIC… … there is no necessity for the lines to leave the core, andthe central space is therefore almost free of lines. We sayalmost, because parallel lines exert a repelling action upon Fig. 22.
