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.
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.
Student experiment exploring Snell’s Law and the Law of Reflection.
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.
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.
Allows mounting and changing of distance between field coils and is used for studies in electromagnetism.
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.
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.
Designed to measure both pulling and pushing forces allowing labs from cart collisions to tug-of-war.
