The problem of fully developed flow and heat transfer in a horizontal channel consisting of an electrically conducting fluid layer sandwiched between two fluid layers is studied analytically. The fluids in all phases are assumed to be incompressible and immiscible. Further the fluids are assumed to have different viscosities and thermal conductivities. The governing differential equations are linear and exact solutions are obtained. The expressions for velocity and temperature distributions are computed numerically for different values of physical parameters and the results are presented graphically. The effect of increasing the Hartmann number M is to decrease the velocity and temperature field. It is found that with suitable values of ratios of viscosities and thermal conductivities, the velocity and temperature can be increased.
