2. 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.

3. Maglev - Wikipedia

   en.wikipedia.org/wiki/Maglev

   Transrapid 09 at the Emsland test facility in Lower Saxony, Germany A full trip on the Shanghai Transrapid maglev train Example of low-speed urban maglev system, Linimo. Maglev (derived from magnetic levitation) is a system of rail transport whose rolling stock is levitated by electromagnets rather than rolled on wheels, eliminating rolling resistance.

4. Electromagnetic suspension - Wikipedia

   en.wikipedia.org/wiki/Electromagnetic_suspension

   Floating globe. Magnetic levitation with a feedback loop. 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 ...

5. Magnetic bearing - Wikipedia

   en.wikipedia.org/wiki/Magnetic_bearing

   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 speeds ...

6. Meissner effect - Wikipedia

   en.wikipedia.org/wiki/Meissner_effect

   Explanation. The Meissner effect was given a phenomenological explanation by the brothers Fritz and Heinz London, who showed that the electromagnetic free energy in a superconductor is minimized provided. where H is the magnetic field and λ is the London penetration depth. This equation, known as the London equation, predicts that the magnetic ...

7. Magnetic level gauge - Wikipedia

   en.wikipedia.org/wiki/Magnetic_level_gauge

   A magnetic level gauge is a level gauge based on a float device that can experience floatation in both high and low density fluids. Magnetic level gauges may also be designed to accommodate severe environmental conditions up to 210 bars at 370 °C. Unlike a sight glass, magnetic level gauges do not need to be transparent and can be made out of ...

8. Magnetic moment - Wikipedia

   en.wikipedia.org/wiki/Magnetic_moment

   m 2 ⋅ A. Dimension. L2I. In electromagnetism, the magnetic moment or magnetic dipole moment is the combination of strength and orientation of a magnet or other object or system that exerts a magnetic field. The magnetic dipole moment of an object determines the magnitude of torque the object experiences in a given magnetic field.

9. Magnetic field - Wikipedia

   en.wikipedia.org/wiki/Magnetic_field

   The shape of the magnetic fields of a permanent magnet and an electromagnet are revealed by the orientation of iron filings sprinkled on pieces of paper. A magnetic field (sometimes called B-field[1]) is a physical field that describes the magnetic influence on moving electric charges, electric currents, [2]: ch1 [3] and magnetic materials.
