We offer a variety of economical ceramic bar, disc, and ring shaped magnets. Magnets are upainted, except where noted.

The unit is used to study electromagnetic induction and transformer principles. The outer coil is 3.25" h x 2.75" d, the inner coil is 3.75"h x 1.25" d. The removable steel core is 4.5" h x 0.5" d. The coils are wrapped with 20 gauge magnet wire and fitted with insulated binding posts. Instructions...

This magnet is generally fed to cows to attract metal particles they may have ingested while grazing. Students can use it in the classroom for magnetic field demonstration and other interesting experiments.

This is a quick and clean way to visualize magnetic fields. The demonstrator is a transparent acrylic case that holds iron filings suspended in a fluid of appropriate viscosity. When it is placed over a magnet, the field pattern can be viewed directly, or it can be placed on an overhead projector...

Use this Compass Board and a magnet (not included) to experiment with magnetism, explore magnetic fields, and learn about the functioning of compasses. Each board contains 20 individual compasses.

This attention-getting demonstration of magnetic repulsion uses a clear acrylic plate that keeps a spinning axle oriented above magnets built into the base of the apparatus. With a simple twist of your fingers, you can start this levitating magnet spinning and kick start a classroom discussion. The...
