Very good Review by
Nice magnets that work well and meet the need of the projects we needed them for... at a decent price too!
Excellent Bar Magnets Review by
These bar magnets are great for demonstrating how poles repel or attract. We also use one or both with iron filings to demonstrate magnetic fields. Put the magnets in small Ziploc bags first and lay on the table. Spread iron filings on a thin sheet of Plexiglas and hold over the magnets to see the magnetic field lines. Any filings trying to stick to the magnet will simply drop free from the Ziploc bag when you remove the magnet. If you let the filings get directly on the magnet you'll never get them off.
Very Nice Magnets Review by
The contrasting paint made these magnets perfect for demonstration purposes in front of my five student class. The are very strong and works great for showing the magnetic field with iron filings.
Great or classroom use Review by
I use these magnets for demonstration of the magnetic field. To make that visible I use metal filings, also obtainable from HST.
