    en.wikipedia.org/wiki/Human_magnetism

    A man with a hammer stuck to his skin. Human magnetism is a popular name for the supposed ability of some humans to attract various objects to their skin.People alleged to have such an ability are often called human magnets.

    They stick together and align themselves into small regions of more or less uniform alignment called magnetic domains or Weiss domains. Magnetic domains can be observed with a magnetic force microscope to reveal magnetic domain boundaries that resemble white lines in the sketch. There are many scientific experiments that can physically show ...

  4. 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 ...

  5. Lodestone - Wikipedia

    en.wikipedia.org/wiki/Lodestone

    The Earth's magnetic field at 0.5 gauss is too weak to magnetize a lodestone by itself. [9] [10] The leading theory is that lodestones are magnetized by the strong magnetic fields surrounding lightning bolts. [9] [10] [11] This is supported by the observation that they are mostly found near the surface of the Earth, rather than buried at great ...

  6. Magnetic stirrer - Wikipedia

    en.wikipedia.org/wiki/Magnetic_stirrer

    A magnetic stirrer or magnetic mixer is a laboratory device that employs a rotating magnetic field to cause a stir bar (or flea) immersed in a liquid to spin very quickly, thus stirring it. The rotating field may be created either by a rotating magnet or a set of stationary electromagnets, placed beneath the vessel with the liquid.

  7. Sticky-shed syndrome - Wikipedia

    en.wikipedia.org/wiki/Sticky-shed_syndrome

    Reel of magnetic audiotape A damaged cassette tape. Sticky-shed syndrome is a condition created by the deterioration of the binders in a magnetic tape, which hold the ferric oxide magnetizable coating to its plastic carrier, or which hold the thinner back-coating on the outside of the tape. [1] This deterioration renders the tape unusable. [2]

  8. Magnetic switchable device - Wikipedia

    en.wikipedia.org/wiki/Magnetic_switchable_device

    A magnetic switchable device (often called a magnetic base) is a magnetic fixture that uses one or more permanent magnets in a configuration that allows the external field to be turned on or off. They are used in many applications including optics , metalworking , lifting , and robotics, to attach items to metal surfaces in a secure but ...

  9. Magnetic tape - Wikipedia

    en.wikipedia.org/wiki/Magnetic_tape

    Magnetic tape is a medium for magnetic storage made of a thin, magnetizable coating on a long, narrow strip of plastic film. It was developed in Germany in 1928, based on the earlier magnetic wire recording from Denmark. Devices that use magnetic tape can with relative ease record and play back audio, visual, and binary computer data.
