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.
A 500-turn wire coil on a bobbin that can accommodate banana plug contacts for measuring current or voltage. It can also be mounted on a PASCO Helmholtz base.
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.
Students can vary propeller type and diameter with this small scale wind turbine. An accessory to the Energy Transfer-Generator.
