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.
Two electrolytic, bi-polar, 25 Volt capacitors with screw terminals.
A 200 turn wire coil on a bobbin that has a base with three terminals that accommodate banana plug contacts for measuring current or voltage. Can be mounted on a Helmholtz base.
Used for measuring the temperature of liquids, air, and other materials. ScienceWorkshop Version.
Teach the science and technology of waves and sound. Harmonic motion, waves, sound, period, frequency, resonance, interference and more.
Consists of two coils mounted on a base to provide a uniform magnetic field between the coils.
Vials contain a vacuum sealed color forming reagent to test a variety of water quality parameters. 30 individual Iron test vials.
When plugged into a detector coil, the LED flashes red or green as the detector coil passes through the magnet to indicate which direction the current flows through the detector coil.
Designed to measure both pulling and pushing forces allowing labs from cart collisions to tug-of-war.
Student experiment using an optics bench to build telescopes for use with a viewing screen.
Comprised of alloy mix of Al, Ni, and Co, is stronger and last longer than Iron magnets.
