Description

This lecture covers the magnetic properties of ferromagnetic materials, focusing on ferromagnetism and paramagnetism. It explains how ferromagnetic materials retain magnetization, creating a permanent magnetic field. The interaction of atomic moments and thermal agitation affecting magnetization are discussed, along with the concept of Curie temperature. The lecture also delves into hysteresis cycles in ferromagnetic materials, explaining saturation magnetization, residual magnetization, and energy loss. Additionally, it explores the applications of ferromagnetic materials in various industries.
