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.

Ring Launcher
The ring launcher consists of a vertically mounted solenoid of thick copper wire with an iron core. The coil is energized with by pressing the push button on the panel. Two aluminum rings are supplied with the apparatus. These rings fit over the solenoid and are supported at some height above the base by adjustable collar. The behaviour of the rings when the coil is energized depends on the type of the ring placed over the coil at the time. The solid aluminum ring is propelled straight up while the slotted ring remains static, thus demonstrating the principle of electromagnetic induction as well as Lenz law.

Eddy Current Kit
This Eddy Current Unit is a compact demonstration apparatus used to study electromagnetic induction and the effects of eddy currents. It features a conductive metallic disc mounted on a rotating shaft, supported by a rigid base. An adjustable arm allows the placement of a magnet close to the rotating disc, enabling users to observe eddy current effects such as magnetic braking, resistance to motion, and energy dissipation. It is ideal for classroom demonstrations of electromagnetic principles in a clear and interactive way.
Features:
- Metallic conductive disc
- Rotating shaft with support
- Adjustable magnet holder arm
- Rigid base with labeling
- Smooth rotation mechanism
