We have studied the levitation of Y-Ba-Cu-O bulk superconductors above a Bi-Sr-Ca-Cu-O superconducting pancake coil with and without the function of the inner coil. It was found that the inner coil with small diameter can enhance the levitation force through its contribution to the radial component of the magnetic field. We also successfully applied the total energy balance method for the understanding of the bulk levitation.
