This paper summarizes the simulation analysis for the repulsion occurring between the permanent magnet. Nowadays, such as magnetic levitation, safety bumper device and so on using the properties of the permanent magnet, and many cases are. The neodymium magnet of a powerful ferromagnetic material are less expensive compared to the strong magnetic force for industrial, medical and etc. can be used in a various applications. The prediction of the magnetic force is becoming increasingly important in order to be used effectively permanent magnet in various fields. Therefore, the results of the magnetostatics of Ansys and the MAXWELL of commercial electromagnetic analysis software are analyzed and compared. Magnetic force is inversely proportional to the distance and power. In this paper, a permanent magnet was simulated and compared-diameter 4mm, 8mm length of the small size of the two permanent magnets. In addition, simulated the forces between the ferromagnetic Iron and permanent magnets.
