  2. 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 ...

  3. 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 ...

  4. Orders of magnitude (magnetic moment) - Wikipedia

    en.wikipedia.org/wiki/Orders_of_magnitude...

    The magnetic moment of an object is an intrinsic property and does not change with distance, and thus can be used to measure "how strong" a magnet is. For example, Earth possesses an enormous magnetic moment, however we are very distant from its center and experience only a tiny magnetic flux density (measured in tesla ) on its surface.

  5. Rare-earth magnet - Wikipedia

    en.wikipedia.org/wiki/Rare-earth_magnet

    Ferrofluid on glass, with a rare-earth magnet underneath. A rare-earth magnet is a strong permanent magnet made from alloys of rare-earth elements.Developed in the 1970s and 1980s, rare-earth magnets are the strongest type of permanent magnets made, producing significantly stronger magnetic fields than other types such as ferrite or alnico magnets.

  6. Orders of magnitude (magnetic field) - Wikipedia

    en.wikipedia.org/wiki/Orders_of_magnitude...

    The magnetic flux density does not measure how strong a magnetic field is, but only how strong the magnetic flux is in a given point or at a given distance (usually right above the magnet's surface). For the intrinsic order of magnitude of magnetic fields, see: Orders of magnitude (magnetic moment). Note:

    en.wikipedia.org/wiki/Talk:Neodymium_magnet

    it seems to me that the confusion is caused by ambiguity of english: "pulling through the hand" could mean: A) that the magnetic field on the other side of the hand is strong enough to pull on a ferromagnetic object or B) that it forces such an object through the hand — Preceding unsigned comment added by 213.49.102.59 14:36, 4 November 2014 ...

  9. Want a Pet Raccoon? Consider This First. - AOL

    When you consider how a raccoon lives in the wild, you can see how difficult it may be to replicate that in your household. For one thing, raccoons are nocturnal, meaning they will be active at night.
