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.
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.
Consists of two coils mounted on a base to provide a uniform magnetic field between the coils.
A rigid pendulum with a coil at the end to be used for induction investigations.
Student experiment using an optics bench to build telescopes for use with a viewing screen.
Two electrolytic, bi-polar, 25 Volt capacitors with screw terminals.
The redesigned Variable Gap Magnet is rugged and durable while providing excellent results as a demonstration tool.
The complete solution for examining the principles of magnetic flux and conservation of energy.
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.
