Falling to Stage lift is a critical injury, so that it must be prevented without experience. To avoid an injury of falling, actors must assure safety by active control. Active control is purpose, regulation, and stop control. To keep show go on, it is required for actors to stop performance before falling. And to avoid stop performance, regulate their position not to access the stage lift. Based on these controls, actors can performance, achieving the purpose. To acquire this control, actors have to practice. And the situation of practice and real running is distinguished clearly because safety measures can be applied on one side, and cannot on other. And control of actors includes a dangerous failure comes from human property. It is must to prevent a critical injury comes from their dangerous failure. To that, it is need to disperse energy, and we purpose a device using both of permanent magnet electromagnet as an example. Because friction force from magnet is constant, it can definitely determine force to depend on the human body.
