Abstract

An analog electronic circuit designed to illustrate the principles of ferromagnetism by simulating the behavior of elementary magnetic dipoles as described by the Langevin-Weiss theory is presented. The device is intended to help undergraduate students master the fundamental ideas that explain the properties of ferromagnetic materials. The circuit design is described and related to the concepts used in the Langevin-Weiss theory, which is briefly outlined. Results obtained with the simulator are presented as oscilloscope traces and illustrate some of its possible uses
