The thermal counterflow in superfluid helium placed in a magnetic field is shown to lead to the emergence of an electric field in the surrounding space. This effect is caused by the counterflow nature of thermal conductivity in superfluid systems: heat transfer in such systems is associated with the motion of the normal component, while the average mass flow transported by the normal component is compensated by the mass flow carried by the superfluid component. The local mass flow is nonzero. The effect occurs in case of stationary and non-stationary (second-sound) heat flows. The features of the effect for a number of samples with various geometries are considered. It was established that the magnitude of the arising electric field substantially depends on the shape of the sample containing helium and the direction of the magnetic field.
