The hub will press fit onto the shaft of many small DC generators; just attach your own blades and begin experimenting with wind power! The hub is designed to allow you to change blade angles and/or interchange blade sets quickly and easily. An improved stainless-steel insert can take a beating in your classroom year after year without failing!

Demonstrate the Stirling Design External Combustion Engine with our 18×11 cm working model. The Stirling engine currently is being re-examined as a practical source of power because of its adaptability to almost any fuel. First produced in the 1800’s as a non-electric fan and an automatic hot air water pump, the engine soon became obsolete due to its lack of sufficient power when compared to the newly developed combustion engine. Any fuel can be used with our model, but denatured alcohol is suggested for clean operation.

Helmholtz coils are used to produce a homogeneous magnetic field. Experiments on induction and electron deflection can be performed with the Rotary Frame with Flat Coil and the Fine Beam Tube. The coils can be used in parallel or in series and feature a spring clip on the cross bar to mount a Hall Sensor for measurements of the magnetic field. The maximum field strength generated by the coils (~ 4 mT) is approximately 750 times weaker than that produced by an MRI machine (~ 3T), which are known to be safe for use by people with medical implants such as pacemakers.

The Vernier Circuit Board 2 is a basic electricity lab on a board. The turret terminals for every component make it easy to connect basic series and parallel circuits, examine the behavior of different components, and investigate RLC circuits. The Vernier Circuit Board 2 includes 10 bulbs, a resettable fuse, three powering options, 10 alligator clip leads, terminal clips to add components, and pre-installed components.
