## Ferrofluid dynamics, magnetic relaxation, and irreversible thermodynamics

The Journal of Chemical Physics. 2010. Vol. 132. No. 18. P. 184907- 1-184907-7.

The dynamics of ferrofluids is discussed on the basis of Maxwell’s equations and the balance equations for mass, momentum, angular momentum, and energy. It is shown that the requirement of irreversible thermodynamics that the local rate of entropy production be positive definite allows equations of motion, and a corresponding magnetic relaxation equation, characterized by free convective parameters.
