This fascinating anti-gravity demonstration works on the principle of repelling magnets and is ideal for discussing magnet levitation and frictional force experiments. With a simple twist of the fingers, the axle spins horizontally in a state of near-perpetual motion for up to 20 minutes. Black and white reflecting strips on the axle allow students to observe the patterns created by the alternating colors and to measure rotation speed using a stroboscope (not included).
• Comes with a Teacher’s Guide
• Batteries are not required
• Approx. 5″ L x 2.5″ W x 3″ H

Made with micron-sized, iron-based particles distributed throughout, the astonishing, moldable Magnetic Thinking Putty takes on the properties of a magnet itself when placed in close contact with the included magnet. It’s perfect for science-loving kids, or for any adult that loves intelligent play! Use the magnet to do the “snake charmer” trick. Or leave the magnet on your ball of putty and watch it completely engulf the magnet in minutes! What can you do with it? The possibilities are endless!
• Comes with a Teacher’s Guide
• Putty (91 g/3.21 oz) comes with a Neodymium cube magnet in storage tin

Item N38

$3.38

The Magnetic Pole Finder is a quick and easy way to demonstrate the 3-dimensional magnetic force field. It consists of a small alnico bar magnet mounted on a gimbal so that it will rotate freely. It is more convenient and accurate than the traditional methods using compasses and iron filings. The Magnetic Pole Finder is perfect for experiments on the forces between magnetic poles, fields around wire and coils and the properties of fields produced by electric currents.
