Magnetic Field Demonstrator
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 line up along the field lines in all dimensions. With Cylindrical Magnet.

Magnetic Field Demonstrator, Acrylic
An elegant method for displaying the shape of magnetic fields without using iron filings. Ideal for student investigations or for demonstration using an overhead projector. The transparent plate is comprised of a matrix of small circular chambers. Each chamber contains an iron rod and functions independently as a plotting compass.

Magnetic Force Accelerator
A ramp with metal sides is filled with permanent magnets, North Pole up, covered with a large label. Three Aluminium tubes of different diameters can be placed in turn across the ramp, connecting the metal sides. A 12 V DC voltage is applied to the sides of the ramp so that a large current flows (up to 15 A). The Aluminium tube is immediately accelerated rapidly along the ramp and shoots off the end, breaking the circuit. As well as confirming the Right Hand Rule, students can observe the difference in the current drawn by the tube when the ramp is horizontal and when one end is raised using the included wooden prop. Requires a power supply that can deliver 12 V DC / 15 A, not included.

Magnetic Pendulum
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 and released, it tends to swing in an erratic, unpredictable pattern. Due to friction, the pendulum eventually comes to rest over one of the magnets.
