Let me ask you a question: Suppose a stationary magnet is placed on a surface. Now bring an iron piece (or any other substance compatible with magnetism) in its force field. With certainty it will be attracted towards magnet. Now Work=force*displacement Hence Work is done by the Magnet to drag the iron piece towards it. Hence Energy is needed to do Work. Here comes the main part........according to law of conservation of energy "energy can only be transformed from one form to another". So.....which form of energy is converted to evolve magnetic force?
