  The general equation for the flux of an electrolyte in solution in the
presence of an external magnetic field was derived mathematically in accordance
with the Onsager formalism of irreversible thermodynamics. The time reversal
symmetry was examined theoretically for the equation. Time reversal symmetry
breaking was demonstrated for the case under investigation. Indeed, it was
demonstrated theoretically that diffusion of an electrolyte is solution under
an applied magnetic field has asymmetry in respect with time. The important of
the study is to show time asymmetry in a physical process based on mathematical
derivation of available equations.
