Abstract: Electromagnetic levitation melting is a processing technology of without crucible high conductivity materials levitation melting. In the process of smelting, avoid contact with the vessel wall, there are many advantages, is indispensable of research and preparation the high purity material. In this paper, we introduce self- developed high conductivity material electromagnetic levitation melting demonstration experiment device and interesting experiment phenomenon. The theoretical analysis for electromagnetic suspension phenomenon is conducted. The electromagnetic levitation force distribution of several different excitation coil structure is calculated numerically. All sorts of experimental phenomena are explained. The experimental device demonstration effect and phenomena reveal physical principle. Which is suitable for intuitive teaching to students for studying physics in school, also suitable for science and technology museum show to young people.

Key words: electromagnetic levitation, melt, demonstration experiment
