Operates on 1.5 to 6 VDC. Lifts up to 3500g. With the current direction indicator for the study of the magnetic field. Dimensions: 12 x 12 x 4cm. Weight: 14oz. Ages 10+
The transparent acrylic chamber contains iron filings. Chamber also has an internal tunnel into which a bar magnet can be inserted to demonstrate a magnetic field pattern. Other shaped magnets can be investigated by positioning their poles near one side of the chamber. With a Cylindrical magnet.
Consist of a closed transparent box with a transparent tube through the center. The box contains iron filings and silicon oil. When one or more cylindrical magnets are inserted into the central tube, the filings are attracted and lined up along the field lines in all dimensions. With Cylindrical Magnet.
A quick and clean way to visualize magnetic fields. The unit is a transparent acrylic case that holds iron filings in a fluid of proper viscosity. The unit can also be placed on an overhead projector for classroom demonstration. Unit measures 8”x 4-1/2” x 3/8”. 11oz. Ages 10+

The Random Oscillating Magnetic Pendulum (ROMP) is a popular desktop toy. It consists of a pendulum, with a small magnet attached to the end, which can swing freely over a metal base. On the base, there are nine numbers of strong, disc-shaped magnets, which act on the pendulum with either an attractive or repulsive force. When the pendulum is displaced…
Strong Ceramic magnets sealed in unbreakable colorful plastic cases. The North and south poles are located on opposite faces for ease of use. Can be used to determine if an object is magnetic. A pair of magnetic wands can be used to demonstrate attraction and repulsion between poles. The wand measures 7.5" x 1". Ages 7+
