Effect of magnetic yoke on magnetic field distribution and intercepting effect of multi-channel cascading magnet arrays
Magnetic-Sieve possesses a potential use in oxygen separation. The effect of a magnetic yoke on magnetic field distribution and intercepting effect of multichannel cascading magnet arrays in a MagneticSieve configuration is studied by ANSYS finite element software. The multi-channel cascading magnet arrays consist of cuboid neodymium-iron-boron permanent magnets. The size of the magnets is WxH=38mmx5mm, and the clearance between two adjacent magnets is lmm. The results show that the intercepting effect tends to decrease from the central channel to the most lateral channels in multi-channel cascading magnet arrays. Compared with the simulation result of two magnets, the central magnetic inductions of the center channel and the most lateral channels in the multi-channel cascading magnet array including 14 magnets decrease respectively 10％ and 31％, and the intercepting effects of the center channel and the most lateral channels decrease 19％ and 60％, respectively. When the magnetic yoke is added on the multi-channel cascading magnet array, the above-mentioned four values are increased by 28％, 29％, 63％ and 65％, respectively. The simulation study shows that the introducing of magnetic yokes can enhance the central magnetic induction and the intercepting effect of the gradient magnetic field, and moreover, reduce the disparities of intercepting effect among the channels.
