Description
Crank a Wimshurst generator to produce large amounts of stored charge. Negative charge will be removed to one side of the generator, leaving other side positively charged. Using this generator is a good fall back for electrostatic demonstrations on humid days.
NOTE:
- Remind students that the overall net charge of generator remains zero.
- Use high voltage wire leads (labeled "Wimshurst leads") to transfer charge to objects
- Take care not to touch any metal portions of the generator.
- Bring Wimshurst "arms" close to each other, but not touching, to observe discharging. On days of low humidity, this discharge could be as long as 3 cm.

Equipment
Wimshurst machine, Small/ Large; High voltage "Wimshurst" leads
