What is langevin theory of diamagnetism
Answers
7.5 Classical theory of diamagnetism [Langevin theory] In this theory, we will obtain an expression for the change in magnetic moment of an orbiting electron in a diamagnetic atom and the induced magnetic moment per unit volume of diamagnetic material in the applied magnetic field B 0.
Through Langevin's theory of diamagnetism we obtain an expression for change in magnetic moment of an orbiting electron in a diamagnetic atom and the induced magnetic moment per unit volume of the diamagnetic material in the applied magnetic field.
This equation is named after Paul Langevin.
Diamagnetic materials are those materials which when placed in a magnetic field get repelled by that magnetic field.
The phenomenon of diamagnetism occurs in all materials and is a quantum mechanical effect. When this effect is related to magnetism only, the material is called diamagnetic.
