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 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.
Consists of two coils mounted on a base to provide a uniform magnetic field between the coils. 200-turn coils.
Designed to measure magnetic field with three selectable ranges of +-1000 gauss.
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.
Allows mounting and changing of distance between field coils and is used for studies in electromagnetism.
Consists of two coils mounted on a base to provide a uniform magnetic field between the coils.
The complete solution for determining the ratio of specific heat capacities for air by measuring the period of oscillation of the piston in a cylinder filled with air.
Used for measuring the temperature of liquids, air, and other materials. ScienceWorkshop Version.
The complete solution for examining the efficiency of heat engines and compared to the ideal gas law.
