混合磁体中悬浮的苹果意味着在梯度磁场下存在微重力条件。然而，在悬浮条件下，发现了一些独特的行为，即悬浮大米颗粒的取向，悬浮铋颗粒的排列以及水中的热对流。这在太空的微重力条件下是不可能的，这是磁悬浮的特征。在了解这些行为的基础上，将磁悬浮应用于无容器材料的加工，并由此尝试开发了磁悬浮炉。
A levitating apple in a hybrid magnet implies the presence of microgravity conditions under gradient magnetic fields. However, several unique behaviors were found, the orientation of levitating rice grains, the alignment of levitating bismuth particles, and the thermal convection in water under the levitation conditions. These are unlikely under the microgravity conditions in the space and are characteristic of the magnetic levitation. On the basis of the understanding of such behaviors, the magnetic levitation was applied to containerless materials processing, and such an attempt resulted in the development of a magnetic levitation furnace.
