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 be used with the Energy Transfer Generator (ET-8771A) to study wind energy.
Consists of two coils mounted on a base to provide a uniform magnetic field between the coils.
Student experiment exploring Snell’s Law and the Law of Reflection.
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.
Students can vary propeller type and diameter with this small scale wind turbine. An accessory to the Energy Transfer-Generator.
Teach the science and technology of waves and sound. Harmonic motion, waves, sound, period, frequency, resonance, interference and more.
The complete solution for examining the principles of magnetic flux and conservation of energy.
The complete solution for examining the relationship between magnetic field strength of current-carrying coils on the distance from the coil along the perpendicular axis.
The complete solution for examining the efficiency of heat engines and compared to the ideal gas law.
The redesigned Variable Gap Magnet is rugged and durable while providing excellent results as a demonstration tool.
