"Suppose that , if the coil ( a lonng coil of wire) presents its south pole to the incoming N pole of a bar magnet . The bar magnet will now be sucked in through the coil at an ever increasing acceleration . Thus , a gentle push of the magnet towards the coil will initiate a process that will continuosly increase its velocity and kinetic energy . By a suitable arrangement, it is possible to do so in a perpitual motion machine . So will it not voilate the law of conservation of energy ......? If no then what happens to the energy where does it come from?????
