Hysteresis loop

Explanation of Hysteresis Loop on the Basis of Domain Theory

Physics /

Hysteresis Loop: The word hysteresis literally means lagging behind. “Hysteresis is the phenomenon of lagging of magnetic induction (B) behind the magnetising field (H) of a ferromagnetic material when the specimen is at critical temperature. It is also defined as when a ferromagnetic material is taken through a cycle of magnetisation, the variation of B (magnetic

Weiss put forward a second hypothesis, namely domain hypothesis. He postulated that the atomic dipole of an atom strongly interacts to the neighbouring atom by a quantum mechanical interaction called exchange interaction. He explain why a sample of ferromagnetic material has spontaneous magnetisation. Explanation The entire ferromagnetic volume splits into a large number of small
