Magnet is found in the earth with iron ore. Where there is magnet in the ore, the iron is of the best quality. The magnet resembles iron.

If you put a piece of iron on a magnet, the iron itself begins to attract other iron. And if you put a steel needle on a magnet, and hold it thus for awhile, the needle will become a magnet, and will attract iron. If two magnets are brought together at their ends, one side will turn away from the other, while the other sides will be attracted.

If a magnetic rod is broken in two, each half will attract at one end, and will turn away at the other end. Cut it again, and the same will happen; cut it again, as often as you please, and still the same will happen: equal ends will turn away from each other, while opposite ends will be attracted, as though the magnet were pushing away at one end, and pulling in at the other. No matter how you may break it, it will be as though there were a bump at one end, and a saucer at the other. Whichever way you put them together⁠—a bump and a saucer will meet, but a bump and a bump, or a saucer and a saucer will not.
