Dynamic behavior of gas flow in gradient magnetic fields

Abstract

The mechanism of the formation of the magnetic curtain which appears in an air atmosphere under gradient magnetic fields is studied. It is assumed that the magnetic curtain is a wall of air produced by the interaction of gradient magnetic fields with paramagnetic oxygen. Gas flow experiments in magnetic fields are carried out. The gas flow is clearly blocked by magnetic fields at 120 T/sup 2//m. A model based on molecular dynamics is proposed to explain the experimental results. Trajectories of gas flows are calculated, and the threshold value of magnetic field strength needed to block nitrogen gas flow is obtained.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
