The study of "magnetoaerodynamics" is important to control airflows. The magnetically induced change in the velocity of O2 gas streams injected into air was quantitatively studied. Whether O2 gas flow was magnetically accelerated or decelerated was found to depend on the sign of the magnetic field gradient applied at the O2 outlet. The magnetically induced change in the velocity Delta nu = mod nu H- nu 0 mod was found to increase by increasing the product of the magnetic intensity and its gradient, H*(dH/dy), and lowering the velocity without the fields, nu 0. The dynamics of this magnetically induced gas flow was explained by considering the magnetic force acting on the paramagnetic oxygen gas. The calculation shows the most efficient acceleration to occur when nu 0=0 cm/s. The result of the present study suggests the possibility of magnetic control of gas streams containing O2 gas. The necessary conditions are the gradient of the O2-gas concentration, the low-velocity without fields, nu 0, and high quantity of H*(dH/dy).
