Increased Levitation Force in Magnetic Levitation System Using Magnetic Shielding Effect of HTS Bulk

We studied a levitation system that uses the magnetic shielding effect of a high-temperature superconducting bulk. As the levitation force was insufficient in our former experiments, ferromagnetic plates and bars were added to the superconducting bulk to increase the levitation force. Experimental r...

Zusammenfassung:	We studied a levitation system that uses the magnetic shielding effect of a high-temperature superconducting bulk. As the levitation force was insufficient in our former experiments, ferromagnetic plates and bars were added to the superconducting bulk to increase the levitation force. Experimental results showed that the levitation force increased when small plates and bars were used. The peak levitation force exceeded the weight of the moving part in our experimental system, thus enabling the moving part to be lifted.
