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...

Spin Stabilized Magnetic Levitation of Horizontal Rotors

In this paper we present an analysis of a new configuration for achieving spin stabilized magnetic levitation. In the classical configuration, the rotor spins about a vertical axis; and the spin stabilizes the lateral instability of the top in the magnetic field. In this new configuration the rotor spins about a horizontal axis; and the spin stabilizes the axial instability of the top in the ma...

Diamagnetically stabilized magnet levitation

Stable levitation of one magnet by another with no energy input is usually prohibited by Earnshaw’s Theorem. However, the introduction of diamagnetic material at special locations can stabilize such levitation. A magnet can even be stably suspended between (diamagnetic) fingertips. A very simple, surprisingly stable room temperature magnet levitation device is described that works without super...

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...

Noncollinear magnetic order stabilized by entangled spin-orbital fluctuations.

Quantum phase transitions in the two-dimensional Kugel-Khomskii model on a square lattice are studied using the plaquette mean field theory and the entanglement renormalization Ansatz. When 3z(2)-r(2) orbitals are favored by the crystal field and Hund's exchange is finite, both methods give a noncollinear exotic magnetic order that consists of four sublattices with mutually orthogonal nearest-n...
