The magnet gun is a simple but spectacular experiment in which a slowly rolling ball sets in motion a sequence involving several magnets and balls, and ends up shooting out a ball at high speed.

For demonstrating the magnetic field around a conductor.

This case contains teaching materials for experiments concerning two closely related topics:Magnets: The students investigate the properties of magnets.

Compass: Experiments with magnets hanging on a stand or floating on a polystyrene base encourage the students to observe and discover how the magnets, like a compass needle, always point north-south.

For investigating the oscillation period of an ideal (simple) pendulum, where the entire mass is in the bob. Consists of two-point suspension, pendulum string and two lenticular bobs of different materials but the same volume.The bobs have different masses, but the same air resistance.
