The Graphical Representation Of Magnetic Theories, Harold N. Allen Jan 1904

The Graphical Representation Of Magnetic Theories, Harold N. Allen

Department of Physics and Astronomy: Dissertations, Theses, and Student Research

The induction theory of magnetism, introduced by Faraday, is now looked upon by all physicists as correct. The older theory which assumes the existence of magnetic fluids covering the ends of the magnet is in some cases mathematically simpler, and is for this reason often made use of. This, however, is apt to breed confusion as to the true nature of the induction or polarization in any given case. The difficulty Tyndall experienced in accepting Faraday's views as to diamagnetism, is accounted for by the fact that he was thinking in terms of the fluid theory, while Faraday was considering …
