Zusammenfassung:It is shown that when the superfluid component of 4He is in motion relative to the quantized vortices of superfluid helium (He II), an electric field appears, caused by the electric properties of the quantized vortices, which are generated by the polarization of the liquid during its motion around the vortex core. In a state of thermodynamic equilibrium and in an isotropic and homogenous liquid such as superfluid 4He, the electric field generated by the quantized vortices is equal to zero. However, anisotropy occurs during the relative motion of the superfluid and normal components, which include quantized vortices, due to the difference in the velocities between the normal and superfluid components. This anisotropy and the electric properties of the quantized vortices lead to the creation of an electric field in He II. The calculated results given in the article are compared to the experimental data.
