1. When two like-poles point together, the arrows from the two magnets point in OPPOSITE directions and the field lines cannot join up. So the magnets will push apart .
2. This is because magnets attract materials that have unpaired electrons that spin in the same direction.
3. If you break a magnet length wise, they will not fit back together because the like poles repel.
4. Place light pressure on the magnet and rub the metal in one direction only. Magnetization will take some time to accomplish so continue rubbing until the iron or steel attracts other pieces of metal. Repeat the magnetization process, as necessary.
