Magnetic Levitation Forces of Superconductors
2019The magnetic levitation force (F) of a superconductor is dependent on its manufacturing process and the specification of a magnet used for the measurement. The F of the melt processed superconductors is very large. For example, the F of the single-grain bulk superconductors measured at liquid nitrogen temperature (77 K) is as large as a hundred newton (

Forces on null-flux magnetic levitation systems
Journal of Applied Physics, 1973Forces on rectangular current-carrying coils, above and below an infinite conducting sheet of arbitrary thickness and moving parallel to it, are investigated. Expressions are given for the lift and drag forces on the coils as a function of speed. Numerical calculations are made and compared with experimental results.

Levitation Force between Superconductors and Magnets
1998It is known that bulk superconductors exhibit a large electromagnetic force (EMF) with the interaction of permanent magnets. We measured the EMF by varying the shape of superconducting bulks and the magnet configuration such as the thickness and the number of poles.

Force Calculation for Hybrid Magnetic Levitation System
2018 14th International Conference on Computational Intelligence and Security (CIS), 2018This paper presents a calculation model for the electromagnetic force of the hybrid magnetic levitation systems composed of electromagnets and permanent magnets, based on which, theoretical derivation is presented for electromagnetic induction intensity distribution of a single solenoid. According to the molecular circulation hypothesis and Biot-Savart

Electrostatic force analysis of electrostatic levitation system
SICE '95. Proceedings of the 34th SICE Annual Conference. International Session Papers, 2002This paper focuses in particular on the lateral electrostatic force characteristic of an electrostatic levitation system as part of the overall system dynamics. The lateral force exerted on a levitated aluminum disk, used in hard disk applications, originating from a relative translation of the disk with respect to the stator electrode, is analytically
