The globe is suspended from an electromagnet. This makes the friction very low and the earth will rotate at a constant speed for many hours after being spun around.
Diameter: 20 cm
AC adapter included.
Allows mounting and changing of distance between field coils and is used for studies in electromagnetism.
Students can vary propeller type and diameter with this small scale wind turbine. An accessory to the Energy Transfer-Generator.
The redesigned Variable Gap Magnet is rugged and durable while providing excellent results as a demonstration tool.
A rigid pendulum with a coil at the end to be used for induction investigations.
Designed to be used with the Energy Transfer Generator (ET-8771A) to study wind energy.
The complete solution for examining the principles of magnetic flux and conservation of energy.
Vials contain a vacuum sealed color forming reagent to test a variety of water quality parameters. 30 individual Iron test vials.
Designed to measure magnetic field with three selectable ranges of +-1000 gauss.
Teach the science and technology of waves and sound. Harmonic motion, waves, sound, period, frequency, resonance, interference and more.
Two electrolytic, bi-polar, 25 Volt capacitors with screw terminals.
