氧气泡在磁场中的磁化力及其氧浓度测量

Magnetic Force of the Oxygen-bubble in Magnetic Field and the Measurement of Oxygen Concentration

利用两块同样大小的钕铁硼永久磁铁在其缝隙中产生的不均匀磁场,对放置于缝隙中的圆管中的一含氧气泡所受到的磁化力大小进行了研究,并根据含氧气泡所受到的磁化力的大小来确定该含氧气泡中的氧浓度.

In this paper, the permanent magnetic field with the equivalent magnetic charge method and the magnetic force of the oxygen bubble in a pipe which is put in the magnet field are calculated. We first calculate the magnetic field, then we calculate a unit volume of material in one-dimensional magnetic field gradient,where the integral is over the material specimen. By ble,we can know the concentration of the oxygen in the calculating the magnetic force of the oxygen bubbubble. This will be more useful in many domain.
