Introduction Magnetochemistry is the study of the magnetic properties of materials. This includes synthesis, analysis and understanding. This short description is meant to give a basic understanding before you delve into a more complex treatment.
Magnetism arises from moving charges, such as an electric current in a coil of wire.
In a material which does not have a current present, there are still magnetic interactions. The processes which create magnetic fields in an atom are Nuclear spin. Some nuclei, such as a hydrogen atom, have a net spin which creates a magnetic field. Electron orbital motion. There is a magnetic field due to the electron moving around the nucleus.
