Abstract

Developments in the production, distribution and control of electrical energy depend very largely on the correct knowledge and understanding of the laws representing the relation of electric current to magnetism. Modern developments in electrical engineering, particularly in the areas of electronic systems, communication equipment like telephones, electrical machinery, and magnetic amplifiers, make it imperative that the study of the behavior of materials under varying magnetic induction be accomplished thoroughly. A detailed study enables one to predict the performance of circuits under extreme test conditions. Although some recently discovered alloys have permeabilities greater than iron, their uses in magnetic circuits are restricted to limited and special fields. Various types of electrical power apparatus like a-c and d-c machines and transformers use mainly iron or steel in the magnetic circuits. Therefore, it becomes very necessary to study the magnetization characteristic of the materials which comprise the magnetic circuits. The design of magnetic circuits can be materially assisted by being able to explain and express the relation between electric current and magnetism by means of equations. (See more in text.)
