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 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.
Consists of two coils mounted on a base to provide a uniform magnetic field between the coils.
Student experiment using an optics bench to build telescopes for use with a viewing screen.
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.
Student experiment exploring Snell’s Law and the Law of Reflection.
Teach the science and technology of waves and sound. Harmonic motion, waves, sound, period, frequency, resonance, interference and more.
Designed to measure magnetic field with three selectable ranges of +-1000 gauss.
Spare compasses for the CASTLE Kit (EM-8624A). Perfect for investigating the magnetic fields around straight wires.
Designed to be used with the Energy Transfer Generator (ET-8771A) to study wind energy.
Consists of two coils mounted on a base to provide a uniform magnetic field between the coils. 200-turn coils.
