Key Concepts

Diamagnetism

Diamagnetism refers to the property of a material whereby it develops an induced magnetic moment in the opposite direction to an applied magnetic field. This behavior arises because all electrons in the material are paired, leading to a very weak repulsion from the magnetic field. The effect is intrinsic to all materials, but in diamagnetic substances it is the dominant behavior, making them slightly repelled by magnetic fields.

Paramagnetism

Paramagnetism is a form of magnetism that occurs in materials with one or more unpaired electrons. In a paramagnetic material, the magnetic moments of the unpaired electrons tend to align parallel to an applied magnetic field, resulting in a weak attraction toward the field. Thermal motion, however, randomizes the alignment, which is why the induced magnetization is only significant in the presence of an external magnetic field.

Magnetic Susceptibility Measurement

Magnetic susceptibility measurement is an experimental technique used to quantify the degree of magnetization in response to an applied magnetic field. For paramagnetic materials, techniques such as SQUID magnetometry, Faraday balance, or Gouy balance are employed to measure the small changes in magnetic flux or the force experienced by the sample in the field, providing insight into the material’s paramagnetic behavior.
