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.
Designed to implement a large variety of basic electrical circuits for experiments.
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.
Spare compasses for the CASTLE Kit (EM-8624A). Perfect for investigating the magnetic fields around straight wires.
A 400 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.
Two electrolytic, bi-polar, 25 Volt capacitors with screw terminals.
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.
Student experiment using an optics bench to build telescopes for use with a viewing screen.
When plugged into a detector coil, the LED flashes red or green as the detector coil passes through the magnet to indicate which direction the current flows through the detector coil.
The complete solution for examining the principles of magnetic flux and conservation of energy.
Used for measuring the temperature of liquids, air, and other materials. ScienceWorkshop Version.
