TAP 411-2: Brush up on magnetism
... Any deflection of the pivoted magnet is detected by a sensor and will set off a bell or a horn inside the cab. This deflection is caused by a pair of magnets embedded in the space between the rails. One is a permanent magnet and the other an electromagnet arranged as in the diagram below. The electr ...

... Let’s say you had a ferromagnet and you measured its magnetic field You applied an external B-field and the dipoles are aligned with the field Now you remove the field but some of the dipoles get “stuck” in their new position. Now you measure the magnetic field of the ferromagnet and find that it is ...

Magnetism
Magnetism is a class of physical phenomena that are mediated by magnetic fields. Electric currents and the magnetic moments of elementary particles give rise to a magnetic field, which acts on other currents and magnetic moments. Every material is influenced to some extent by a magnetic field. The most familiar effect is on permanent magnets, which have persistent magnetic moments caused by ferromagnetism. Most materials do not have permanent moments. Some are attracted to a magnetic field (paramagnetism); others are repulsed by a magnetic field (diamagnetism); others have a more complex relationship with an applied magnetic field (spin glass behavior and antiferromagnetism). Substances that are negligibly affected by magnetic fields are known as non-magnetic substances. These include copper, aluminium, gases, and plastic. Pure oxygen exhibits magnetic properties when cooled to a liquid state.The magnetic state (or magnetic phase) of a material depends on temperature and other variables such as pressure and the applied magnetic field. A material may exhibit more than one form of magnetism as these variables change.
