Abstract In this paper we will analyse the feromagnetism in nanoparticles. We will try to explain why materials that do not exhibit magnetism at large scales, exhibit magnetism when nanoparticles of the same material are formed. This occurs because when the particle size is reduced, only one domain can form in one nanoparticle. These nanomaterials then exhibit magnetism at a large scale
