Abstract

It is shown that in a magnetic field the quantized vortices in a superfluid acquire a real quantized electric charge concentrated in the vortex core. This charge is compensated by an opposite surface charge located at a macroscopic distance from the vortex axis. It is found that the polarization caused by the vortex velocity field does not give rise to electric fields outside an infinite cylinder. The vortex-created electric fields can be observed only near the cylinder end surfaces which must be closed with dielectric covers to prevent superfluid leaking. The influence of cover properties on the vortex-created potential is studied. The potentials created by vortices on point and ring electrodes are calculated.
