Abstract: Electromagnetic Levitation (EML) is a kind of technology for containerless processing of material. It has a lot of advantages, such as no contamination, processing materials with higher melting point, stronger erodibility and easy concreting nucleus. The important levitation is to produce big levitating force against gravity on the ground, and to compensate the remaining gravity in space. In this paper, the distribution of levitating force produced by loops is calculated. A stable potential well is also studied and produced to capture the sample. The calculation is mainly focused on the relation between the distribution of levitating force and the structure of loops, such as the number of turns, the angle of wimble, the radius of loop, the space and screw-pitch between loops. A series of curves representing the properties of different structures and the theoretical support for actual loop designs have finely been tend.
