Introduction to Magnets— Super Value Laboratory Kit
In this hands-on introductory kit, students experiment with bar magnets to visibly
see why magnets “stick” to certain objects but not others. They test magnetic polarity and determine what types of materials are magnetic and which are not. Lastly, students sprinkle iron filings over the magnets to clearly display the invisible magnetic fields that surround all magnets. All materials are reusable.

Make a Print of a Magnetic Field— Student Laboratory Kit
Combine science with art to create perma- nent prints of a magnetic field with special photosensitive paper, iron filings and bar magnets. Combine them in various arrange- ments to explore lines of force during attraction and repulsion. Expose the photo- sensitive paper to sunlight or a UV lamp, and students can develop prints with just tap water. Includes instructions with student handouts, Teacher Notes and materials for 30 prints.

Neodymium Magnet
Unbelievably strong magnet! Watch your fingers if you bring two of them together! These ceramic magnets are a perfect exam- ple of how technology is producing new materials with space-age properties. These crystalline, ceramic cobalt-neodymium magnets retain their magnetic strength much longer than normal soft metal magnets and emit their strength to other materials easily. Your students will be totally impressed with the strength of this magnet. 12 mm in diameter.
