Diamagnetic materials are those that are typically attracted to a magnetic field but repel it. The orbital angular momentum of electrons in an atom comes from their rotation around the nucleus. An atom of the diamagnetic material has no residual magnetic momentum.
Let us check out the Properties of Diamagnetic Materials
- In diamagnetic material, there are no atomic dipoles because the resultant magnetic moment of each atom is zero as a result of paired electrons.
- Because the substances are only weakly attracted to the field, they tend to move from a strong to a weak region of the external magnetic field.
- A magnet repels materials that are diamagnetic.
- The relative permeability is slightly less than one.
- The extent of the magnetic field is negligibly small, inversely correlated with the magnetic field, and negative.
- There is negligible and low magnetic susceptibility.
- Materials that are diamagnetic are not temperature dependent. These substances do not adhere to curies law.
- Liquid collects in the middle, where the field is weakest if a liquid is placed on a watch glass placed over two pole pieces that are sufficiently apart.
- When a diamagnetic rod is suspended in a uniform magnetic field, it comes to rest with its length perpendicular to the field direction because the field is strongest at the poles.
- Small and in opposition to the magnetic field H, the magnetic dipole moment.
- When a diamagnetic liquid is placed in a watch glass that is positioned on two pole pieces that are very close to one another, the liquid collects at the sides and displays a depression in the center, where the field is strongest.
- The induced dipole moment, which results from the applied field changing the orbital motion of electrons in atoms, is the source of diamagnetism.
