Paramagnetiset
Paramagnetism is a form of magnetism that occurs only in the presence of an external magnetic field. Materials exhibiting paramagnetism are weakly attracted to this external field. This attraction arises from the presence of unpaired electrons within the atoms or molecules of the material. Each unpaired electron possesses a magnetic dipole moment. In the absence of an external magnetic field, these individual magnetic moments are randomly oriented, resulting in no net magnetization for the material.
When an external magnetic field is applied, the magnetic moments of the unpaired electrons tend to align
The susceptibility of paramagnetic materials is positive but small, and it decreases with increasing temperature. This
