Alinco magnets are made up of Aluminum, Nickel and Cobalt. They are very strong and are ideal for a variety of scientific experiments.
Alinco Bar and Cow Magnets are perfect for demonstrating the magnetic lines of force. Simply cover the magnet with a piece of paper, then sprinkle iron filings over the top and watch them form into the lines of force. Alinco Cow Magnets are really used in vows to prevent "hardware disease."
