Current Density Probes

The theory, construction, and characteristics of a filament-type current density probe are described. Its application to the direct measurement of the magnitude and phase of current density in solid and liquid two-and three-dimensional geometries is presented. The use of scaled liquid models in the solution of a variety of important proximity and skin effect problems is discussed. Brief mention is made of an alternate transducer, called a toroidal-type probe, for use in liquid conductors.
