 ... pole N induces a south pole at A, and the effect of this at any point P of the magnet is opposite and nearly equal to that of the original north pole. In the case of a horse-shoe magnet a single piece of soft iron is placed across the poles, and the...

...Bodies which have a high coefficient of magnetisation may be regarded as good conductors of magnetism. When a piece of soft iron is placed in a magnetic field the lines of force gather themselves up and run in greater quantities through the space now occupied... | |

...of soft iron is placed across the poles, and the same effect is produced. We have already seen that when a piece of soft iron is placed in a magnetic field the lines of force are concentrated through the iron. When a single bar magnet is alone lines of force... | |

...other cases. One important principle can be illustrated most conveniently by this means. It is that when a piece of soft iron is placed in a magnetic field, it has the effect of drawing the lines of force into it (more or less). This is a consequence of the manner... | |
