Magnetization and Magnetic Intensity

चुंबकीकरण एवं चुंबकीय तीव्रता

In Class 12 Physics, under the chapter Magnetism and Matter, students learn how an external magnetic field produces magnetization in a material. The topic defines magnetization as magnetic dipole moment per unit volume and magnetic intensity as the magnetising field, with their SI unit and vector nature. It develops the relation B = μ₀(H + M), introduces magnetic susceptibility and permeability, and connects these ideas with the diamagnetic, paramagnetic, and ferromagnetic behavior of substances.
