All electrons, nucleons, and other particles undergo a persistent spin motion without possessing any infinite energy source, and therefore, they should have a unique structure that maintains their spinning and provides all the properties that they display. Additionally, because nothing in nature occurs without a reason or purpose, there should be an explanation for their persistent spinning motion. Therefore, the unique structures of electrons and nucleons, and purpose why they display persistent spinning motion have been determined. The results of these determinations provide the knowledge of a new force possessing characteristics of nuclear force and both attractive and repulsive components, and very clear and complete explanation of: 1) all the phenomena; 2) all the properties and effects of their systems; and 3) structures of their systems, e.g., deuterons, alpha particles, and nuclei; those are generated due to these particles. Present study is focussed on to provide understanding of how in substances at their transition temperature, resistance-less state, superconducting state, numerous properties, and effects, e.g., Meissner effect, levitation of magnet above the superconductor, and Josephson’s tunnelling, those the substances exhibit at their transition temperature, are generated.
