Properties of Diamagnetism
Properties of diamagnetism are:
- Diamagnetic materials have a slightly negative magnetic susceptibility and a lower relative permeability than unity.
- They have all paired electrons, and none of the electrons is valence, resulting in absence of atomic magnetic moments.
- Diamagnetic materials do not obey Curie’s Law.
- Diamagnetism is a fundamental property of all matter, although it is often overshadowed by other, stronger magnetic effects such as paramagnetism and ferromagnetism.
- Diamagnetic materials can be found in solids, liquids, and gases.
- Diamagnetic materials have a very low or minimal magnetic effect due to the absence of unpaired electrons.
Magnetic Susceptibility (of Magnetic Materials at 20°C)
Magnetic susceptibility measures how much a material will become magnetized in an applied magnetic field. It is the ratio of magnetization M (magnetic moment per unit volume) to the applied magnetizing field H. Magnetic susceptibility indicates whether a material is attracted into or repelled out of a magnetic field.
At 20°C, magnetic susceptibility of some materials are as follows:
|

Bismuth |
-16.6 |
|
Mercury |
-2.9 |
|

-2.1 |
Diamagnetism
Diamagnetism is the property of materials that are repelled by a magnetic field. When an applied magnetic field creates an induced magnetic field in these materials in the opposite direction, it causes a repulsive force.
