Excerpt from Magnetic Fields of Force, Vol. 1: An Exposition of the Phenomena of Magnetism, Electro-Magnetism, and Induction Based on the Conception of Lines of Force
The value of considerations concerning energy are still disputed by some; but it cannot be denied that the conception of energy plays a very important part in electrodynamics. It can be shown that the essential difl'erence between the two theories as to the nature of electrical and magnetic fields is to be found in the expression for the energy in each separate volume element of the region concerned. An exposition of the principles of the localisation and migration of energy has been given here as being in the highest degree fruitful and suggestive; and the most important applications of the subject - the production of currents by induction, the working of motors, and the exertion of force - depend upon the transformation of mechanical forms of energy into energy of the electro-magnetic field, and conversely. Since the consideration of these energy-transformations plays so fundamental a part in this book, I might have chosen for its title Magnetic Fields of Energy.' In naming it, however, I have confined myself to one factor of the energy, the force; because the distribution of energy can be mapped out by means of the faraday-maxwell lines of force or lines of induction alone.
The symmetrical properties of a field which is the seat of magnetic actions decide upon the tenability or untenability of a dynamical hypothesis or a diagrammatic representa tion designed to elucidate the nature of magnetic stress.

Verkäuferbewertung 5 von 5 Sternen
Paperback. Zustand: New. Print on Demand. This book delves into the fascinating world of magnetism and electricity, exploring the fundamental principles that govern these forces. The author takes a unique approach, using the concept of "lines of force" as a framework to explain the various phenomena, drawing inspiration from the groundbreaking work of Faraday and Maxwell. The book's journey begins with the exploration of natural magnets, examining the properties of lodestone and its ability to attract iron. Through a series of carefully designed experiments, the author reveals the intricate patterns of magnetic fields and introduces the concept of polarity. The text then progresses to the creation of artificial magnets, detailing the process of magnetization and the differences in magnetic behavior between iron and steel. A key emphasis is placed on the role of energy within the magnetic field. The book examines how magnetic forces exert work, and how energy is localized within the field itself. The author underscores the importance of visualizing the magnetic field as a dynamic entity, a "field of energy," driven by cyclical motions within the magnet and its surrounding space. This book provides a deep dive into the intricate workings of magnetism, offering a compelling and accessible understanding of a fundamental force that shapes our world.
