Electrolytic Tank Analog for Magnetic Field Design

Abstract
An electrolytic tank serves as a relatively easy and reasonably accurate method of analoging magnetic field configurations. A simplified tank has been constructed for designing a field to be used in a plasma containment device. The tank is useful in determining the parameters for the field producing coils and for mapping isogaussic surfaces that may result when a high density plasma is present in the magnetic field. In this analog tank, the current density in the electrolyte is directly proportional to the magnetic flux density and, from this relationship, equations have been derived by which flux density, magnetomotive force, total flux, inductance, and energy of the coils can be found from tank measurements. The detailed analysis of a specific magnetic field problem is given.
