Electric self-inductance of quasi-two-dimensional magnetic-dipolar-mode ferrite disks Academic Article uri icon


  • An electric current flowing around a loop produces a magnetic field and hence a magnetic flux through the loop. The ratio of the magnetic flux to the electric current is called the (magnetic) self-inductance. Can there be a dual situation with a magnetic current flowing around a loop and producing an electric field and hence an electric flux through the loop? Following the classical electrodynamics laws an answer to this question should be negative. Nevertheless, special spectral properties of magnetic-dipolar modes in a quasi-two-dimensional ferrite disk show that there are the double-valued-function loop magnetic currents which may produce eigenelectric fields and hence eigenelectric fluxes through the loop. In this case one can definitely introduce a notion of an electric self-inductance as the ratio of the electric flux to the magnetic current. In this paper we show experimentally that in the magnetic-dipolar-mode ferrite disks there exist eigenelectric fluxes. These fluxes are very sensitive to the p...
