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 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.
Teach the science and technology of waves and sound. Harmonic motion, waves, sound, period, frequency, resonance, interference and more.
The redesigned Variable Gap Magnet is rugged and durable while providing excellent results as a demonstration tool.
The complete solution for examining the efficiency of heat engines and compared to the ideal gas law.
