Magnetic levitation of liquid helium

Czechoslovak Journal of Physics, 1996
We report on the stable levitation of liquid helium drops of up to 2 cm diameter in a magnetic trap at temperatures down to 1.5 K in the earth's gravitational field. The production and properties of a magnetic trap for diamagnetic materials is discussed.

Basic Study of a Magnetically Levitated Conveyer Using Superconducting Magnetic Levitation

IEEE Transactions on Appiled Superconductivity, 2005
This paper discusses a newly developed conveyer that uses superconducting levitation. The conveyer is composed of a levitated stage with a permanent magnet (PM) and a superconductor with an electromagnet and a Hall sensor. The gap between the PM stage and the superconductor is detected by using the Hall sensor and the current of the electromagnet coil.

Magnetically levitated transportation

Cryogenics, 1971
Abstract Magnetic levitation by means of mutual repulsion between a travelling superconductive magnet and induced eddy currents is explained. Schemes involving different configurations of magnet and ground conductor along with methods of obtaining the lift and drag forces are given.

Magnetic levitation

2015
The paper deals with magnetism and its influence on superconducting materials. We describe the discovery and development of superconductivity, superconducting levitation and its use in future technology - called. MAGLEV speed trains. We show the interaction of the magnetic field of a strong neodymium magnet and high-temperature superconductor, cooled ...

Permanent Magnetic Levitation and Stability

2001
Magnetic levitation applications are becoming more prevalent because permanent magnetic materials have improved in recent years, and their intrinsic instability can be conveniently hindered. In this paper the best current magnetic materials, the rare earths and especially the NdFeB alloy, are presented.

Passive Levitation in Alternating Magnetic Fields

SIAM Journal on Applied Mathematics, 2003
Summary: We analyze stability of a levitated axisymmetric top carrying a system of permanent magnets in an alternating magnetic field. We show that there are stable configurations where the top is stationary, and the alternating magnetic field stabilizes the equilibrium position.

A magnetically levitated motor

SPEEDAM 2010, 2010
We describe a motor which is built on a floating axle technology. The motor has exactly one point of friction and the weight of the motor can be balanced against the magnetic field supporting it. We report the design, a model of operation, and the real performance. Limitations in sensor reaction speed and the effect of drag tend to limit speed.

Stability of magnetic levitation

Journal of Applied Physics, 1978
The levitation forces on metal spheres in magnetic fields of axial symmetry are derived theoretically. Criteria for stability of the center of mass are obtained. It is shown for nonmagnetic samples that the desirable coil configurations are those which provide a constant field gradient along the symmetry axis. The formalism is applied to model coils of
