What is magnetism? Photo: The magnetic field between the opposite poles of two bar magnets that strongly attract one another. We can't normally see magnetic fields, but if you sprinkle iron filings (tiny bits shaved off an iron bar with a file) onto a piece of paper and hold it above the magnets you can see the field underneath.
