Abstract

This letter describes the effect of a heavy current pulse, of approximately 10 kA, produced by a charge capacitor bank, on a small volume of liquid metal, confined in a cylindrical container (tube diameter is 1 cm and tube length is about 10 cm). The liquid metal contamination implies the presence of microscopic nonconducting particles. Theoretical consideration shows that a typical heavy current pulse of 15 msec duration leads to extremely large Lorentz force, due to the appearance of a self-induced magnetic field. Even though the particle contaminants are of micron size they can be moved by this force to macroscopic distances. Such a motion phenomenon can be used in the development of a cleanliness control system.
