Explanation:

Exchange interaction includes the phenomenon of quantum mechanical interaction. It is the phenomenon where it gives the energy of two elementary particles. These effects of exchange arise from all kinds of elementary particles. There are three main contributions to exchange interaction between electrons.

• Spin – dependent electron-electron Coulomb repulsion short distance (antiferromagnetic),
• long distance (ferromagnetic) and also
• spin – dependent electron-nuclear Coulomb attraction.
