The thermal boundary layer on an exponentially stretching continuous surface with an exponential temperature distribution in the presence of magnetic field effect is investigated numerically. The local similarity solution is applied to the governing equationes. The obtained results are verified with the results of earlier authors. Temperature distribution and local Nusselt number have been presented at different values of the governing parameters. In particular, the magnetic field decreases the temperature difference at the wall of the stretching surface while the Nusselt number decreases with it.
