STRONGER THAN A BAR MAGNET: This 2-inch magnet can lift up to 3x more than a bar magnet - up to four pounds! Try it on any ferrous metal and see just how powerful it is. AMAZING MAGNETIC EXPERIMENTS: Explore attraction (note: repulsion can demagnetize horseshoe magnets), compare the strength of different magnets, view invisible magnetic fields using iron filings, and more! GREAT FOR AT-HOME & CLASSROOM SCIENCE: Perfect for at-home explorations, science centers, after school science clubs, and more! INCLUDES PROTECTIVE KEEPER: Store magnet with keeper in place to protect its magnetism. Remove keeper before use. - TOUGH BUT FRAGILE: Like all Alnico magnets, this magnet will break if dropped and become desensitized with magnetic repulsion. Store away from electronics, high heat, and direct sunlight. Store with keeper on.
