Magnetic Induction

—The communication of magnetism to iron by the mere presence of a magnet without actual contact, an action similar to electrostatic induction. If a short thin unmagnetized bar of iron be placed near some iron filings, and a magnet be brought near the bar, magnetism will be induced in the bar by the presence of the magnet. It will be found that the iron bar thus magnetized has two poles; the pole nearest the pole of the magnet being of the opposite kind and the pole at the further end of the bar being of the same kind.
