Loudspeaker in cabinet 20W
Loudspeaker on rod, 3 W
Loudspeaker on rod, 3 WUsed with function generator FR-250350 or FR-250310 to generate sound from a point source. With two speakers you can demonstrate interference.
Loudspeaker, two-way
Loudspeaker, two-wayLoudspeaker for experiments with tone, auditory perception and hearing. (For interference experiments, we recommend 250500 Loudspeaker on post instead.) Fitted with safety sockets.
Lung function model
Lung function modelThis user-friendly lung model shows in a very clear way what happens when we breathe in and out.
Magnaprobe
MagnaprobeA Magnaprobe is used to investigate magnetic fields between the same and different poles, the direction of magnetic fields around a conductor or coil, the sizes of magnetic fields produced by an electric current etc.
Magnet gun
Magnet gunThe 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.
Magnet mount for motor/generator
Magnet mount for motor/generatorUsed for mounting the stator magnets in the motor/generator set.
Magnet set
Magnet setThe set includes a wide selection of different magnets and materials for experiments with magnets and magnetic forces.

Magnets and compasses ? CVK case
Magnets and compasses ? CVK caseThis 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.
Magnets, super
Magnets, superExperience the huge pull of these super magnets. They are designed to allow students to safely use neodymium magnets themselves.
