K. S. Krishnan's magnetic susceptibility theory

K. S. Krishnan’s magnetic susceptibility theory explains how materials respond to magnetic fields based on their atomic structure. It describes how the electrons within atoms can create tiny magnetic fields when exposed to an external magnetic field, influencing the overall magnetic behavior of the material. Depending on how these electrons are arranged and how easily their magnetic moments align, materials can be classified as diamagnetic, paramagnetic, or ferromagnetic. Krishnan's theory helps to predict a material's magnetic susceptibility, which measures how strongly it becomes magnetized in a magnetic field, by considering the electronic and atomic properties of the material.
