What is Superparamagnetism?
{{Orphan|date=May 2009}} '''Superparamagnetism''' is a form of [[magnetism]]. A superparamagnetic material has many small clusters of [[magnetic]] things in its structure, but they are not all pointed the same way, so the material is not [[magnetic]] by itself. If a [[magnetic]] field is applied to the material, then the clusters change direction to match the magnetic field and the material becomes [[magnetic]]. Superparamagnetism is like paramagnetism, except it can happen at near room temperature. It happens when materials are made up of very small parts (1-10 nm). {{science-stub}} [[Category:Magnetism]]
