The magnetic character of domains comes from the presence of even smaller units, called dipoles. While. Explanation: This theory was proposed by Weiss, in the year of 1907.; According to this theory, the magnetic substance is made up of a large number of small domains. He made the following two assumptions: (i) Weiss assumed that a ferromagnetic specimen contains a number of small regions (domains) which are spontaneously magnetized. axes of the domains point in all directions at random and so the bar as a whole shows no polarity. The preparation of the present English version of the revised edition was started in 1985 and took about ten years.
