Some problems of the theory of current probes

Consideration is given to probes used to measure the current of radio frequency interference. Expressions are derived for calculating the inductance of the winding of a current probe as well as the mutual inductance between this winding and an interference-carrying conductor arbitrarily situated relative to the probe. These expressions are then used to investigate the conditions under which the eccentricity of the interference-carrying conductor as well as a nearby current-carrying conductor affect measurement results to a maximal degree.
