Novel Concept of Concentrator of Magnetic Energy

Abstract

This paper presents a novel way of improving the magnetic system arrangement and efficiency via application of the Hall drift for the generation of additional magnetic field and an increase in the magnetic energy density. Such an increase may be realized with the use of a hyperconducting pure aluminum concentrator installed into a traditional solenoid. The Hall drift stimulated by the Lorentz force in crossed electric and magnetic fields has been investigated as a previously ignored source of magnetic field. The properties of the Hall drift of electrons and the generation of an associated self magnetic field are examined with aluminum conductors. An experiment on aluminum disk-like conductors with radial current between the inner and outer concentric contacts has been performed in an axial magnetic field. An analytical study has been made on the fundamental relations of charge flow in electric and magnetic fields under appropriate boundary conditions. The benefits and advantages of the application of the Hall drift magnetic field are discussed for the cryogenic temperature range.
