Abstract
The first intentional memristor was physically realized in 2008 and the memcapacitor in 2019, but the realization of a meminductor has not yet been conclusively reported. In this paper, the first physical evidence of meminductance is shown in a two-terminal passive system comprised primarily of an electromagnet interacting with a pair of permanent magnets. The role of series resistance as a parasitic component which obscures the identification of potential meminductive behavior in physical systems is discussed in detail. Understanding and removing parasitic resistance as a "resistive flux" is explored thoroughly, providing a methodology for extracting meminductance from such a system. The rationale behind the origin of meminductance is explained from a generalized perspective, providing the groundwork that indicates this particular element is a realization of a fundamental circuit element. The element realized herein is shown to bear the three required and necessary fingerprints of a meminductor, and its place on the periodic table of circuit elements is discussed by extending the genealogy of memristors to meminductors.
