A method for measuring partial inductance

Abstract

This paper presents and validates a method for measuring partial inductance with a set of measurement data in comparison to their corresponding exact analytic solution for samples of round wires of different lengths. The concept of partial inductance was introduced and known as a mathematical concept and often perceived “not measurable”, which has been the primary reason for a debate on the existence of the partial inductance. This paper demonstrates that partial inductance exists and is measurable, and also validates the known analytic equations for self- and mutual partial inductance for wires having round and rectangular cross sections with a set of measurement data.
