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.
Designed for experiments involving low light level conditions. ScienceWorkshop version.
A rigid pendulum with a coil at the end to be used for induction investigations.
Student experiment using an optics bench to build telescopes for use with a viewing screen.
Students can vary propeller type and diameter with this small scale wind turbine. An accessory to the Energy Transfer-Generator.
Comprised of alloy mix of Al, Ni, and Co, is stronger and last longer than Iron magnets.
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.
The complete solution for examining the principles of magnetic flux and conservation of energy.
The redesigned Variable Gap Magnet is rugged and durable while providing excellent results as a demonstration tool.
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.
