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.
The redesigned Variable Gap Magnet is rugged and durable while providing excellent results as a demonstration tool.
Students can vary propeller type and diameter with this small scale wind turbine. An accessory to the Energy Transfer-Generator.
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.
A 200 turn wire coil on a bobbin that has a base with three terminals that accommodate banana plug contacts for measuring current or voltage. Can be mounted on a Helmholtz base.
The complete solution for examining the efficiency of heat engines and compared to the ideal gas law.
A 2000 turn wire coil on one end of a wand that has two terminals at the other end to accommodate banana plug contacts, permitting easy connection of an electric circuit.
Vials contain a vacuum sealed color forming reagent to test a variety of water quality parameters. 30 individual Iron test vials.
Used for measuring the temperature of liquids, air, and other materials. ScienceWorkshop Version.
Student experiment using an optics bench to build telescopes for use with a viewing screen.
