Wimshurst Machine 5A50.10
The Wimshurst Machine is located in the Electrostatics Cabinet, A4.
Make sure the two terminals are not touching each other.
Turn the crank. A spark should jump between the terminals as long as they are within about 5 cm.
To discharge the Wimshurst when done: use the insulating handles to bring the terminals together. A spark will likely jump when you do this. The spark from our Wimshurst is lower voltage, though possibly higher current, than from our Van de Graaff, and is unlikely to cause injury.
