The effect of additional permanent magnet magnetizing methods on magnetic field distribution and the levitation force of single domain GdBCO bulk superconductor
It has been investigated that the interaction force between a cubic permanent magnet PM1 and a GdBCO bulk(HTSC) superconducting permanent magnet(SCPM) magnetized by a cubic permanent magnet PM2 under different configurations at 77 K.Two configurations were used for the magnetization of the GdBCO bulk,one is that the North pole of the PM2 is in upward direction,the other is in downward direction,so that the North pole of the SCPM is in two states SCPM↑ and SCPM↓;the vertical distance between the bottom surfa...
