Influence of Heat Treatment on Magnetic Chracteristics of the Magnetic

Magnetic materials in relay have been found to change in their magnetic characteristics with heat treatment. This paper describes how the magnetic characteristics of Magnetic Iron are affected by heat treatment. The materials are pot annealed and cooled from high temperature in the pot, by exposing in the atmospheres, and by quenching in the water and oil. It also studies the best heating temperature and cooling method which improve the magnetic characteristics of the Magnetic Iron.
