... Clouds get their charges as water and ice particles move and interact. Smaller, positively charged particles rise to the top of the cloud and larger, negatively charged particles gather at the bottom. When the buildup of charge is great enough, the oppositely charged particles attract and discharge ...

... Any magnet, no matter what its shape, has two ends called poles. A pole is the area of a magnet where the magnetic effect is strongest. One pole of a magnet points towards magnetic north of the earth and is labeled north. The other pole is labeled south. Although magnetic forces are strongest at the ...

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.
