Noun
a magnet in the form of a bar with magnetic poles at each end
Source: WordNetA permanent magnet, such as a bar magnet, owes its magnetism to the intrinsic magnetic dipole moment of the electron. Source: Internet
For a bar magnet, the direction of the magnetic moment points from the magnet's south pole to its north pole, Knight, Jones, & Field, "College Physics" (2007) p. 815 and the magnitude relates to how strong and how far apart these poles are. Source: Internet
For example, for a long, skinny bar magnet with its north pole at one end and south pole at the other, the magnetic field near either end falls off inversely with the square of the distance from that pole. Source: Internet
Magnetic force Magnetic lines of force of a bar magnet shown by iron filings on paper main The phenomenon of magnetism is "mediated" by the magnetic field. Source: Internet
Magnetic monopoles main Since a bar magnet gets its ferromagnetism from electrons distributed evenly throughout the bar, when a bar magnet is cut in half, each of the resulting pieces is a smaller bar magnet. Source: Internet
A special type of zero-center ammeter for testing high currents in cars and trucks has a pivoted bar magnet that moves the pointer, and a fixed bar magnet to keep the pointer centered with no current. Source: Internet
