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.
Two electrolytic, bi-polar, 25 Volt capacitors with screw terminals.
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 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.
PASCO’s Light Sensor is ideal for indoor and outdoor relative light intensity experiments.
Designed for experiments involving low light level conditions. ScienceWorkshop version.
