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 for experiments involving low light level conditions. ScienceWorkshop version.
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.
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.
