Diaelectric material as permanent magnet: Frog levitation from magnet

Abstract

We previously derived direct-current type negative dielectric susceptibility χ, a state which was termed “diaelectric” in previous work. One candidate for a strong diaelectric material was postulated to be a permanent magnet. According to conventional theories, superconductors or room temperature diamagnets can be thought of as fingers or frogs as in the case of frog levitation by magnets and magnetic levitation between fingertips as explained in previous studies. In this study, we regard magnets as anti-electric materials such that this diaelectric phenomenon may satisfy all conditions necessary to repel the external charges outside the magnet. This dielectric state stems from the concept of an image charge in which the opposing charge may be induced by an external charge that is referenced to a centered plane, and the concurrent same polar charge then coexists as a counterpart of the dipole in the image charge portion, thus repelling the external charge. The resulting finite magnetic fields in permanent magnets may stem from non-zero permanent dipole currents.
