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.
A 400 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.
Student experiment exploring Snell’s Law and the Law of Reflection.
Consists of two coils mounted on a base to provide a uniform magnetic field between the coils. 200-turn coils.
Designed to measure magnetic field with three selectable ranges of +-1000 gauss.
The redesigned Variable Gap Magnet is rugged and durable while providing excellent results as a demonstration tool.
Consists of two coils mounted on a base to provide a uniform magnetic field between the coils.
When plugged into a detector coil, the LED flashes red or green as the detector coil passes through the magnet to indicate which direction the current flows through the detector coil.
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.
Students can vary propeller type and diameter with this small scale wind turbine. An accessory to the Energy Transfer-Generator.
Allows mounting and changing of distance between field coils and is used for studies in electromagnetism.
