... ends of bar magnets and the tips of the horseshoe magnets, are the strongest parts of the magnet. Each magnet has a north pole and a south pole. Opposite poles attract each other (pull toward each other), and same poles repel (push away from each other). So a north pole and a ________________ south ...
