The idea is really simple, but it might not come out in words the same. Is the energy produced from a magnet pushing another magnet away GREATER than the energy needed for a magnet to enter a magnetic field from the side? I'll try to be more specific. You have two magnets, one in your left hand and one in your right hand, who's north poles (or south) are facing each other, so they will be pushed away when they get too close. If you put keep their orientation (left magnets north is facing right, and right magnets north is facing left) and put the left magnet above the right magnet, then "slide" or push the right magnet up into the left magnets magnetic field so that it gets pushed to the right, will the energy of the magnet being pushed to the right as it enters the left magnets magnetic field be GREATER than the energy it took to push the right magnet into the left magnets magnetic field?
