... When applying an external magnetic field, domains with magnetization parallel to the field will grow at the cost of domains with energetically more unfavorable magnetization alignment. As a consequence domain walls move through the sample and the overall magnetization increases. In magnetically soft ...

... By convention, the N end of a bar magnet is what points at the Earth’s North Geographic Pole. Since opposite poles attract (analogous to opposite electric charges), the “North Geomagnetic Pole” is in fact a magnetic SOUTH pole, by convention. Confusing, but it’s just a convention. Just remember that ...

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.
