The wonders of science never cease to amaze. For those of us who are easily impressed, magnets still exert a tremendous force on us. Though students are aware of what happens when you chase one magnet with another, few are aware of what happens to a magnet when you drill a hole through it. Does it open a wormhole? Does it give birth to a black hole? No. But the end results will surprise the curious and astound the skeptical.
Put your eye protection on.
Clamp the magnet into a bench vise, leaving about an inch of the magnet exposed. Use a magnet that is about an inch in diameter or an inch square.
