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.
A rigid pendulum with a coil at the end to be used for induction investigations.
Designed for experiments involving low light level conditions. ScienceWorkshop version.
Used for measuring the temperature of liquids, air, and other materials. ScienceWorkshop Version.
The redesigned Variable Gap Magnet is rugged and durable while providing excellent results as a demonstration tool.
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.
