Dirac-Pauli equations

The Dirac-Pauli equations describe how particles like electrons behave when they have a property called spin and an electric or magnetic moment. They extend the original Dirac equation by incorporating the particle’s magnetic interactions, providing a more accurate picture of their behavior in electromagnetic fields. This helps explain phenomena such as the tiny magnetic moment of electrons and their interactions with magnetic environments. Essentially, these equations combine principles of quantum mechanics and relativity to model the detailed dynamics of spinning, charged particles in electromagnetic forces.
