It is shown that in a magnetic field quantized vortices in a superfluid obtain 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 determined that the polarization caused by the vortex velocity field does not give rise to electric fields outside an infinite cylinder. Observation of electric fields created by the vortices is possible only near the end surfaces of the cylinder which must be closed with dielectric covers to prevent superfluid leaking. Influence of cover properties on the potential created by the vortex is researched. Potential created by the vortices on point and ring electrodes are calculated.
