Magnetic Properties of Materials

पदार्थों के चुंबकीय गुण

This Class 12 Physics topic from Magnetism and Matter explains how materials respond to an external magnetic field. Students learn the meaning of magnetization, magnetic susceptibility, and permeability, and distinguish diamagnetic, paramagnetic, and ferromagnetic substances through their atomic or molecular behavior. The topic also introduces magnetic domains, saturation, retentivity, coercivity, and hysteresis, helping students understand permanent magnets, electromagnets, and practical magnetic materials.
