A strong magnetic field is applied perpendicular to the plate and the plate temperature oscillates in time about a constant non-zero mean. The problem has been solved for the velocity and temperature fields and the effects of β e (the Hall parameter), β i (the ion-slip parameter),E r (rotation parameter), and Ω have been discussed and shown graphically.enArticle
