2. Spin-stabilized magnetic levitation - Wikipedia

   en.wikipedia.org/wiki/Spin-stabilized_magnetic...

   Spin-stabilized magnetic levitation is a phenomenon of magnetic levitation whereby a spinning magnet or array of magnets (typically as a top) is levitated via magnetic forces above another magnet or array of magnets, and stabilised by gyroscopic effect due to a spin rate that is neither too fast, nor too slow to allow for a necessary precession.

3. 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]

4. Ferrite (magnet) - Wikipedia

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

   These so-called ceramic magnets are cheap, and are widely used in household products such as refrigerator magnets. The maximum magnetic field B is about 0.35 tesla and the magnetic field strength H is about 30–160 kiloampere turns per meter (400–2000 oersteds). [33] The density of ferrite magnets is about 5 g/cm 3.

5. Maximum energy product - Wikipedia

   en.wikipedia.org/wiki/Maximum_energy_product

   In magnetics, the maximum energy product is an important figure-of-merit for the strength of a permanent magnet material. It is often denoted ( BH ) max and is typically given in units of either kJ/m 3 (kilojoules per cubic meter, in SI electromagnetism) or MGOe (mega- gauss - oersted , in gaussian electromagnetism ).

6. Superconducting magnet - Wikipedia

   en.wikipedia.org/wiki/Superconducting_magnet

   In 2017, a YBCO magnet created by the National High Magnetic Field Laboratory (NHMFL) broke the previous world record with a strength of 32 T. This is an all superconducting user magnet, designed to last for many decades. They hold the current record as of March 2018.

7. Programmable magnet - Wikipedia

   en.wikipedia.org/wiki/Programmable_magnet

   Correlated magnets can be programmed to interact only with other magnetic structures that have been coded to respond. Correlated magnets can even be programmed to attract and repel at the same time. Compared to conventional magnets, the correlated magnet provides much stronger holding force to the target and stronger shear resistance.
