Paramagnetic

Paramagnetic materials are those materials that are weakly attracted to an external magnetic field. These materials have unpaired electrons, which means that the magnetic moments of the individual atoms do not completely cancel each other out. As a result, paramagnetic materials are attracted to magnetic fields, although the attraction is relatively weak compared to ferromagnetic materials.

Properties of Paramagnetic Materials

1. Paramagnetic materials are weakly attracted to magnetic fields.
2. These materials have unpaired electrons, resulting in a net magnetic moment.
3. Paramagnetic behavior is temperature-dependent and decreases as temperature increases.
4. Paramagnetic materials do not retain magnetism once the external magnetic field is removed.

Examples of Paramagnetic Materials

Examples of paramagnetic materials include oxygen, aluminum, platinum, and titanium.
