  2. Artificial gravity - Wikipedia

    en.wikipedia.org/wiki/Artificial_gravity

    They were able to generate a small amount of artificial gravity, about 0.00015 g, by firing their side thrusters to slowly rotate the combined craft like a slow-motion pair of bolas. [10] The resultant force was too small to be felt by either astronaut, but objects were observed moving towards the "floor" of the capsule. [11]

  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. Neodymium magnet - Wikipedia

    en.wikipedia.org/wiki/Neodymium_magnet

    The greater forces exerted by rare-earth magnets create hazards that may not occur with other types of magnet. Neodymium magnets larger than a few cubic centimeters are strong enough to cause injuries to body parts pinched between two magnets, or a magnet and a ferrous metal surface, even causing broken bones. [46]

  5. Ferrite (magnet) - Wikipedia

    en.wikipedia.org/wiki/Ferrite_(magnet)

    Due to ceramic ferrite magnet’s weaker magnetic fields compared to superconducting magnets, they are sometimes used in low-field or open MRI systems. [41] [42] These magnets are favored in certain cases due to their lower cost, stable magnetic field, and ability to function without the need for complex cooling systems. [43]

  6. Programmable magnet - Wikipedia

    en.wikipedia.org/wiki/Programmable_magnet

    Programmed magnets can be programmed, or coded, by varying the polarity and/or field strengths of each source of the arrays of magnetic sources that make up each structure. The resulting magnetic structures can be one-dimensional, two-dimensional, three-dimensional, and even four-dimensional if produced using an electromagnetic array.

  7. Magnetic levitation - Wikipedia

    en.wikipedia.org/wiki/Magnetic_levitation

    Magnetic levitation can be stabilised using different techniques; here rotation (spin) is used. Magnetic levitation (maglev) or magnetic suspension is a method by which an object is suspended with no support other than magnetic fields. Magnetic force is used to counteract the effects of the gravitational force and any other forces. [2]

  9. Horseshoe magnet - Wikipedia

    en.wikipedia.org/wiki/Horseshoe_magnet

    The shape of the magnet was originally created as a replacement for the bar magnet as it makes the magnetic field stronger for a magnet of comparable strength. [5] A horseshoe magnet is stronger because both poles of the magnet are closer to each other and in the same plane which allows the magnetic lines of flux to flow along a more direct path between the poles and concentrates the magnetic ...
