Magnetic Properties: Materials and Magnetization

This lecture covers the magnetic properties of materials, focusing on magnetic moments, magnetization, and susceptibility. It explains the interaction between magnetic moments, different types of magnetism like paramagnetism and diamagnetism, and the behavior of materials below the Curie temperature. The concept of ferromagnetic materials, hysteresis curves, and applications of ferromagnetics are also discussed. Additionally, the lecture touches on the characterization of ceramics, dielectrics, and magnetic materials, as well as the distinction between dia-, para-, and ferro-magnetic materials. Students will learn about electric and magnetic dipoles, polarization, coercive field, and how to interpret hysteresis curves.
