Spontaneous spinning of a magnet levitating over a superconductor
J.E. Hirsch, D.J. Hirsch
TL;DR
This paper reports the discovery of a spontaneous spinning motion of a magnet levitating over a superconductor, revealing a novel physical phenomenon that overcomes air friction resistance.
Contribution
It explains the physics behind the spontaneous spinning of a levitating magnet, a previously unobserved effect in superconductor-magnet interactions.
Findings
Magnet spontaneously spins over superconductor
Spinning persists despite air friction
Provides a physical explanation for the effect
Abstract
A permanent magnet levitating over a superconductor is found to spontaneously spin, overcoming resistance to air friction. We explain the physics behind this remarkable effect.
