Magnetic Levitation and Noncoalescence of Liquid Helium

Magnetic Levitation and Noncoalescence of Liquid Helium.

Spin stabilized magnetic levitation

The stability of the Levitron cannot be explained if the top’s axis has a fixed direction in space. Stability against flipping is not enough. Gyroscopic precession around the local magnetic field direction is necessary. An analysis and numerical integration of the equations of motion for an experimental stemless top that includes gyroscopic precession around the local magnetic field lines predi...

MAGNETIC LEVITATION A Review

This paper deals with the present scenario of magnetic levitation with LIM. The magnetically levitated train has no wheels, but floats-or surfs-on an electromagnetic wave, enabling rides at 330 miles per hour. By employing no wheels, maglev eliminates the friction, and concomitant heat, associated with conventional wheel-on-rail train configurations. There are two basic types of non-contact Mag...

we used dbsa and nano-magnetic for the synthesis of amido alkylnaphtols.

Vitrification and levitation of a liquid droplet on liquid nitrogen.

The vitrification of a liquid occurs when ice crystal formation is prevented in the cryogenic environment through ultrarapid cooling. In general, vitrification entails a large temperature difference between the liquid and its surrounding medium. In our droplet vitrification experiments, we observed that such vitrification events are accompanied by a Leidenfrost phenomenon, which impedes the hea...
