In a gradient of magnetic field, magnetic
dipoles of the air are attracted toward the region of intense
field such that the air pressure is more in the regions of more
intense field. The formed pressure gradient exerts a net force on
a body placed in the air in this gradient of magnetic field toward
the region of low pressure or the region having weaker field. This
is like what takes place in sink-float separation. If so, we may construct an innovative instrument for separating oxygen from air.
