Abstract
The gradual development of a thin liquid film on the surface of a rota ting disk is studied analytically when the thermocapillary force is in action in the presence of a transverse magnetic field It is Sound tha t the acting thermocapillary force has a profound effect in enhancing the thinning rate of the film even in, the presence of large Hartmann number M. A physical explanation of this result is provided. Large amo unts of fluid are depleted in a small span of time when the Hartmann n umber M is small.
