  2. Magnet - Wikipedia

    en.wikipedia.org/wiki/Magnet

    A magnet's magnetic moment (also called magnetic dipole moment and usually denoted μ) is a vector that characterizes the magnet's overall magnetic properties. For a bar magnet, the direction of the magnetic moment points from the magnet's south pole to its north pole, [ 15 ] and the magnitude relates to how strong and how far apart these poles ...

  3. Magnetic storage - Wikipedia

    en.wikipedia.org/wiki/Magnetic_storage

    Magnetic storage or magnetic recording is the storage of data on a magnetized medium. Magnetic storage uses different patterns of magnetisation in a magnetizable material to store data and is a form of non-volatile memory. The information is accessed using one or more read/write heads.

    BTDigg was founded by Nina Evseenko in January 2011. The site is also available via the I2P network and Tor.In March–April 2011, several new features were introduced, among them web plugin to search with one click, qBittorrent plugin, showing torrent info-hash as QR code picture, torrent fakes and duplicates detection, and charts of the popular torrents in soft real-time.

  5. Molecule-based magnets - Wikipedia

    en.wikipedia.org/wiki/Molecule-based_magnets

    Molecule-based magnets (MBMs) or molecular magnets are a class of materials capable of displaying ferromagnetism and other more complex magnetic phenomena. This class expands the materials properties typically associated with magnets to include low density, transparency, electrical insulation, and low-temperature fabrication, as well as combine magnetic ordering with other properties such as ...

  6. Neodymium magnet - Wikipedia

    en.wikipedia.org/wiki/Neodymium_magnet

    This magnetic energy value is about 18 times greater than "ordinary" ferrite magnets by volume and 12 times by mass. This magnetic energy property is higher in NdFeB alloys than in samarium cobalt (SmCo) magnets, which were the first type of rare-earth magnet to be commercialized. In practice, the magnetic properties of neodymium magnets depend ...

  7. Electromagnetism - Wikipedia

    en.wikipedia.org/wiki/Electromagnetism

    Magnetic poles (or states of polarization at individual points) attract or repel one another in a manner similar to positive and negative charges and always exist as pairs: every north pole is yoked to a south pole. [8] An electric current inside a wire creates a corresponding circumferential magnetic field outside the wire.

  9. Magnetic reluctance - Wikipedia

    en.wikipedia.org/wiki/Magnetic_reluctance

    Magnetic reluctance, or magnetic resistance, is a concept used in the analysis of magnetic circuits. It is defined as the ratio of magnetomotive force (mmf) to magnetic flux . It represents the opposition to magnetic flux, and depends on the geometry and composition of an object.
