Magnetism Magnetic Field Viewer Viewing a magnetic field is quick and easy with this credit cardsized laminate enclosing a suspension of minute iron particles in oil. The small particle size defines the shape of the magnetic field more precisely than filings and reveals the poles of weak magnets as well. P8-1152 Magnetic Field Viewer $2.95 P8-1153 Field Viewing Film, 9" x 7.2" $17 Levitating Globe A breakthrough in magnetic levitation! Suspended in mid-air, this 4" globe defies gravity — inspiring wonder and amazement. The Levitating globe is the ULTIMATE conversation piece. Museum quality and design with a futuristic effect makes this a must-have for home or office. Included with each globe is a mirror base and a 12 volt power supply. P8-3200 Levitating Globe $89 Magnetic Globe Simulate the Earth’s magnetic field with the Magnetic Globe. Place used staples or Magnetic Chips (page 44) at different points. If they lay flat, you’ve found the magnetic equator; if they stand up, you’ve located a magnetic pole. Between the poles and the equator, the staples or chips will stand at different angles. Using the gimbalmounted Magnaprobe (below), you can also demonstrate how the magnetic field extends beyond the surface of the globe. P8-1130 $12 Discovery Pack Magnetism Discovery Pack Investigate magnetic poles, magnetic field lines, and magnetic forces with this fun collection. Painted Steel Bar Magnets, 1 pair Horseshoe Magnet Floating Magnets Strobe Revolution Magnetic Chips Iron Filings Saver Magnetic Seal Magnetic Globe Magnaprobe Clear Compasses, 20-pk. Instructions & Lesson Ideas Magnaprobe This gimbal-mounted bar magnet makes an easily manipulated, high-sensitivity indicator for studying three-dimensional magnetic force fields. Quicker, easier, and more accurate than plotting with compasses or iron filings, it’s ideal for experiments on magnetic induction, forces between poles, fields around wire and coils, properties of fields produced by electric current, and much more. Individually packaged with complete instructions. P8-8005 $17.95 Moves like a 3-D compass needle. P8-9025 $99 They chirp. They whirrr. They are mysteriously irresistible! They seem simple enough — two finely polished, high powered, oval shaped magnets. Each is about 2.5 inches long. But pull them apart, toss them in the air, bring them next to each other — and they enthusiastically come to life! Driven by powerful magnetic attraction and repulsion, these space age looking ellipsoids continually strive to stay in perfect balance with each other. This magnetic balancing act results in a wide variety of mysterious chirping noises that are at once both unnerving and mesmerizing. P8-1150 Magnetoids $5 pair Remagnetizer Unlike expensive, traditional electric remagnetizers, this device uses two permanent, powerful neodymium magnets to add new life to both your dead magnets and your budget. Within seconds, weakened horseshoe and bar magnets are restored to their original magnetic capabilities! Durably constructed with a steel base and aluminum frame, the Remagnetizer can be mounted to a table or wall for added convenience. Simply match up the opposite poles of a Revitalize your horseshoe magnet weakened by repeated and bar magnets in experiments or mistreatment and seconds,without electricity. you’re back in business. 42 visit arborsci.com for: > FREE Downloadable Product Demos! > Secure Credit Card and P.O.
