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.
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.
The redesigned Variable Gap Magnet is rugged and durable while providing excellent results as a demonstration tool.
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.
Two electrolytic, bi-polar, 25 Volt capacitors with screw terminals.
Designed to be used with the Energy Transfer Generator (ET-8771A) to study wind energy.
A rigid pendulum with a coil at the end to be used for induction investigations.
Designed to implement a large variety of basic electrical circuits for experiments.
Consists of two coils mounted on a base to provide a uniform magnetic field between the coils. 200-turn coils.
Designed to measure both pulling and pushing forces allowing labs from cart collisions to tug-of-war.
