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.
Designed for experiments involving low light level conditions. ScienceWorkshop version.
The redesigned Variable Gap Magnet is rugged and durable while providing excellent results as a demonstration tool.
Designed to be used with the Energy Transfer Generator (ET-8771A) to study wind energy.
Comprised of alloy mix of Al, Ni, and Co, is stronger and last longer than Iron magnets.
Vials contain a vacuum sealed color forming reagent to test a variety of water quality parameters. 30 individual Iron test vials.
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.
Spare compasses for the CASTLE Kit (EM-8624A). Perfect for investigating the magnetic fields around straight wires.
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.
The complete solution for examining the efficiency of heat engines and compared to the ideal gas law.
