Recent relativistic heavy-ion collision experiments have found evidence for the generation of strong magnetic field and global angular momentum. The numerical simulation of evolution of the QCD medium is based on either magnetohydrodynamics or spin-hydrodynamics for calculation of observables pertaining to magnetic field or global angular momentum, respectively. However, these two effects are not entirely separable due to the possible spin alignment of medium constituents in the presence of magnetic field, similar to the Einstein-de Haas effect. Therefore, a unified framework of “spin-magnetohydrodynamics” needs to be developed for precise calculation of experimental observables. The first formulation of this unified framework in a relativistic context will be presented starting from the development of spin hydrodynamics.
