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.
Teach the science and technology of waves and sound. Harmonic motion, waves, sound, period, frequency, resonance, interference and more.
The complete solution for determining the ratio of specific heat capacities for air by measuring the period of oscillation of the piston in a cylinder filled with air.
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 for experiments involving low light level conditions. ScienceWorkshop version.
