The majority of studies of transient laminar magnetohydrodynamic (MHD) free convection over a vertical isothermal plate concern gases and air. The existing results for water have been produced assuming a linear relationship between fluid density and temperature. However, it is known that the density relationship for water is nonlinear at low temperatures. In this study, the problem of transient laminar MHD free convection over a vertical isothermal plate in water is investigated in the temperature range between 20 °C and 0 °C. The results are obtained with the numerical solution of the boundary layer equations. Comparison with previous works shows excellent agreement. The variation of the magnetic field parameter has strong effects on the results.
