Magnetic and electrical properties of pure iron wire.

The following paper describes an investigation of the magnetic and electrical properties of some specimens of iron wire of different degrees of purity and hardness. Magnetic Properties. The chief information sought in this part of the investigation was the manner in which the various magnetic constants varied with the character of the iron, and to whatextent they were changed by annealing the specimen. The magnetic quantities under observation were induction, permeability, hysteresis loss, and Steinmetz coefficient. [...
