Abstract: Angular momentum conservation in magnetic fluids is formulated within a rigorous, hydrodynamic theory. The fluid is treated as an isotropic liquid in a magnetic field: Neither the domain spin nor the mesoscopic vortices are accepted as legitimate variables. The only vorticity quantity is Ω = 12rotν, although traditionally (Ω−12rotν) ≠ 0 is thought to be the fundamental cause of all the ferrofluid peculiarities. The stress tensor is derived to be symmetric, despite ferrofluids being quite famous for their asymmetric stresses. An internal angular momentum, finally, is shown to not exist, although ferrofluids are usually regarded as the best-confirmed example of systems to have one.
