The flow of a viscous, incompressible, and electrically conducting fluid past an inclined elliptic cylinder in a parallel magnetic field is discussed, making use of a perturbation method similar to Oseen approximation. Approximate formulas for the forces experienced by the cylinder are obtained only tc the lowest order of the Reynolds number and the magnetic Reynolds number. The drag and lift coefficients are then expressed as functions of flve nondimensional parameters, i.e., the Reynolds number, the magnetic Reynolds number, the pressure number, the thickness-ratio and the angle of incidence of the cylinder. Numerical calculations for the drag and lift coefficients as well as their ratio are carried out for various values of these five parameters. It may be noted in the numerical results that the angle of incidence of the cylinder at which the lift coefficient has a maximum value increases with the increase of the pressure number S when S < 1, and the reverse is the case when S> 1.
