Spin-Electromagnetics and Spin-Gravity

The spin of electrons is studied (Spintronics) and applied to, for example, quantum computing. In this article, utilizing UMFT (Universal Mathematical Field Theory), we establish both Spin-Electromagnetics (Spin-EM) from the Coulomb’s law and the spin of electric source, and Spin-gravity from the Newton’s law and the spin of the gravity-g-charge (mass). Spin-EM predicts several new effects including the Spin-Lorentz-type force, and Spin-Lagrangian-Lorentz-type force. When experimentally confirmed, the Spin-force would be a NEW FORCE. The UMFT has been established and utilized to derive the Maxwell electromagnetics (Maxwell-EM) and Maxwell-type gravity (Gravito-EM). UMFT shows that mathematical identities lead to physical dualities, such as the duality between Maxwell-EM, Gravito-EM, Spin-EM, and Spin-gravity. The well-known-concepts, effects, and phenomena of Maxwell-EM may be directly converted to that of Spin-EM and Spin-Gravity. The Maxwell-EM, Gravito-EM, Spin-EM, and Spin-gravity are all derived from UMFT and thus, they are dual to each other, and can be unified in the frame of UMFT.
