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.
Designed to be used with the Energy Transfer Generator (ET-8771A) to study wind energy.
Designed to measure both pulling and pushing forces allowing labs from cart collisions to tug-of-war.
Spare compasses for the CASTLE Kit (EM-8624A). Perfect for investigating the magnetic fields around straight wires.
Students can vary propeller type and diameter with this small scale wind turbine. An accessory to the Energy Transfer-Generator.
Student experiment using an optics bench to build telescopes for use with a viewing screen.
A 2000 turn wire coil on one end of a wand that has two terminals at the other end to accommodate banana plug contacts, permitting easy connection of an electric circuit.
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.
Student experiment exploring Snell’s Law and the Law of Reflection.
Vials contain a vacuum sealed color forming reagent to test a variety of water quality parameters. 30 individual Iron test vials.
