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.
Student experiment using an optics bench to build telescopes for use with a viewing screen.
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.
The complete solution for examining the efficiency of heat engines and compared to the ideal gas law.
Students can vary propeller type and diameter with this small scale wind turbine. An accessory to the Energy Transfer-Generator.
Spare compasses for the CASTLE Kit (EM-8624A). Perfect for investigating the magnetic fields around straight wires.
Designed to implement a large variety of basic electrical circuits for experiments.
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.
Teach the science and technology of waves and sound. Harmonic motion, waves, sound, period, frequency, resonance, interference and more.
Designed to be used with the Energy Transfer Generator (ET-8771A) to study wind energy.
