Increase of Levitation Properties on Magnetic Levitation System Using Magnetic Shielding Effect of GdBCO Bulk Superconductor

We have studied a magnetic levitation system using magnetic shielding effect of a superconducting bulk made of gadolinium. We extended the experimental apparatus from the previously used basic model to parallely placed 2-basic model. The peak levitation force in the 2-basic model was more than double the force in the basic model due to the bending of magnetic force lines. We could successfully obtain the large levitation force.
