2. Magnetic levitation - Wikipedia

   en.wikipedia.org/wiki/Magnetic_levitation

   Therefore, ferrofluids, with a max bearing pressure in the order of 2 x 104, have been studied to increase the amount of weight that magnetic force can pull. A study by Hsu [2] demonstrated that a ferrofluid-controlled microrobot was able to carry 130 times the mass of its bare magnet counterpart.

3. Magnetic gear - Wikipedia

   en.wikipedia.org/wiki/Magnetic_Gear

   A third-order magnetic gear is a rotational device, where a mode-2 device is modified to have external field coil(s). The external coils create a harmonic flux when powered with multiple-phase AC, which behaves like a variable number of stator rods, thus effecting a variable transmission or variable ratio magnetic gear. This type of gear ...

4. 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.

5. Magnetic bearing - Wikipedia

   en.wikipedia.org/wiki/Magnetic_bearing

   A magnetic bearing. A magnetic bearing is a type of bearing that supports a load using magnetic levitation. Magnetic bearings support moving parts without physical contact. For instance, they are able to levitate a rotating shaft and permit relative motion with very low friction and no mechanical wear. Magnetic bearings support the highest ...

6. 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.

7. Electromagnetic suspension - Wikipedia

   en.wikipedia.org/wiki/Electromagnetic_suspension

   Electromagnetic suspension (EMS) is the magnetic levitation of an object achieved by constantly altering the strength of a magnetic field produced by electromagnets using a feedback loop. In most cases the levitation effect is mostly due to permanent magnets as they have no power dissipation, with electromagnets only used to stabilise the effect.
