5A 10.10 - Glass and Plastic Rods with Silk and Fur
Demonstrates: Electrostatics.
Description: Rubbing the rod with silk or fur charges the rod which then attracts the rod on the stand.
5A 10.20 - Electrophorus
Demonstrates: Charge transfer and storage.
Description: A charge can be created by hand and stored for later use.
5A 20.10 - Spin Electroscope
Demonstrates: Electric fields.
Description: Bringing a charged rod near one of the needles causes it to start spinning.
5A 20.20 - Pith Ball Electroscope
Demonstrates: Positive and negative charges.
Description: Charge is transferred to the balls which then repel each other.
5A 20.30 - Suspended Copper Rod
Demonstrates: Electrostatics.
Description: The copper rod is attracted by the glass rod and repelled by the plastic rod.
