I ve been searching for formula I need for so long so I came here. SO: I need a formula that expresses mehanic energy needed to levitate another magnet by electromagnet. Idea is to express electric energy needed to levitate a magnet using electromagnet and than convert electric energy needed to mehanical energy. Allso I want to know what parameters do you need to calculate this energy (like mass). P.s. Eanglish is not my first language so if I didn't specify something or left something unclear, please ask me what I ment. Thanks for your help
