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.
Student experiment using an optics bench to build telescopes for use with a viewing screen.
The complete solution for examining the principles of magnetic flux and conservation of energy.
Designed to measure magnetic field with three selectable ranges of +-1000 gauss.
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.
Designed to measure both pulling and pushing forces allowing labs from cart collisions to tug-of-war.
Consists of two coils mounted on a base to provide a uniform magnetic field between the coils.
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.
Vials contain a vacuum sealed color forming reagent to test a variety of water quality parameters. 30 individual Iron test vials.
The redesigned Variable Gap Magnet is rugged and durable while providing excellent results as a demonstration tool.
