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 ...
Diamagnetically levitated milli- and micro-robots offer precise control and minimal force noise, ensuring intrinsic stability and efficient zone control. Leveraging diamagnetic levitation, these robots experience reduced sliding friction and can achieve full levitation when paired with a diamagnetic layer, such as graphite, in the presence of a ...
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.
An active magnetic bearing (AMB) works on the principle of electromagnetic suspension and consists of an electromagnet assembly, a set of power amplifiers which supply current to the electromagnets, a controller, and gap sensors with associated electronics to provide the feedback required to control the position of the rotor within the gap ...
A magnetically levitated (maglev) train departing Shanghai Pudong International Airport on the first commercial high-speed maglev line in the world. Magnetic levitation is in development for use for transportation systems. For example, the Maglev includes trains that are levitated by a large number of magnets. Due to the lack of friction on the ...
Electrodynamic bearings (EDB) are a novel type of bearing that is a passive magnetic technology. EDBs do not require any control electronics to operate. They work by the electrical currents generated by motion causing a restoring force.
The Meissner effect - The Feynman Lectures on Physics Meissner Effect (Science from scratch) Short video from Imperial College London about the Meissner effect and levitating trains of the future. Introduction to superconductivity Video about Type 1 Superconductors: R = 0/Transition temperatures/ B is a state variable/Meissner effect/Energy gap ...
Levitated optomechanics is a field of mesoscopic physics which deals with the mechanical motion of mesoscopic particles which are optically or electrically or magnetically levitated. Through the use of levitation, it is possible to decouple the particle's mechanical motion exceptionally well from the environment.
