5.12″ diameter device for measuring temperature, humidity, and barometric pressure.
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 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.
Two electrolytic, bi-polar, 25 Volt capacitors with screw terminals.
Spare compasses for the CASTLE Kit (EM-8624A). Perfect for investigating the magnetic fields around straight wires.
Designed to measure magnetic field with three selectable ranges of +-1000 gauss.
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.
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.
Designed to measure both pulling and pushing forces allowing labs from cart collisions to tug-of-war.
