摘要：
A model has been proposed for calculating the temperature of spherical samples levitated in the general levitation inducers under the protection of inert gas. Considering the limits of levitation force and sample temperature, a spherical (TbDy)Fe2 sample under the protection of argon gas was examined, and the effect of structural parameters of levitation inducers, radius of levitation sample and frequency of power on the stable levitation zone was investigated. The present analysis enables us to improve the levitation stability by increase of the radius of samples, the turns and coning, the radius of down levitation-coil and decrease of the space length of down levitation-coil.
