Magnet - definition of Magnet in Encyclopedia (919 words) |
 | Such materials consist of atoms or molecules that have each a magnetic field (resulting from the spin angular momentum of electrons within them), but objects composed of these materials have magnetic fields only to the extent that these microscopic magnetic fields are positioned to reinforce rather than cancel each other. |
| There are theories involving the possibility of north and south magnetic monopoles, which could be mounted at the ends of, say, a wooden rod to produce a dipole magnet. |
| Calculating the attractive or repulsive force between two magnets is, in the general case, an extremely complex operation, as it depends on the shape, magnetisation, orientation and separation of the magnets. |
