bar magnet

Each muon behaves like a tiny bar magnet when exposed to a magnetic field, an effect called the magnetic moment.

If the latter is in the form of a helix its magnetic field resembles that of a straight bar magnet.

To illustrate Lenz's Law, suppose that the north-seeking pole of a bar magnet be inserted in a closed coil of wire.

A cylindrical magnet, which is substantially the same as a horseshoe, might be substituted with advantage for the bar magnet.

The general facts of magnetism are most simply illustrated by a magnetized bar of steel, commonly called a bar magnet.

Placing a small magnetic needle near a bar magnet, it takes a determinate position.
