When Was Paramagnetism Discovered?

Paramagnetism, kind of magnetism characteristic of materials weakly attracted by a strong magnet, named and extensively investigated by the British scientist Michael Faraday

beginning in 1845. Most elements and some compounds are paramagnetic.

What is the origin of paramagnetism?

Paramagnetism is due to the presence of unpaired electrons in the material, so most atoms with incompletely filled atomic orbitals are paramagnetic, although exceptions such as copper exist. ... An external magnetic field causes the electrons' spins to align parallel to the field, causing a net attraction.

What is Curie law of paramagnetism?

According to the Curie law of paramagnetism, the strength of magnetization in any paramagnetic material varies inversely with the temperature applied to the material, which means the more the temperature of the paramagnetic material is, the lesser will be magnetization in the material.
