Pith Ball Electroscope
Model Number: MTEE-15
The Pith Ball Electroscope is a simple electrostatic apparatus consisting of a pair of lightweight balls suspended from a rod mounted on an insulated base. It is designed to provide a visible response to electrostatic charge and can be used for experiments involving charge detection, attraction, repulsion, and interaction between charged objects.
Product Specification
Product Description
The Pith Ball Electroscope is a practical apparatus designed for observing and investigating basic electrostatic phenomena. Its lightweight suspended balls respond readily to nearby charged objects, providing a clear visual indication of electrostatic interaction.
The apparatus consists of a pair of lightweight balls suspended by fine threads from a supporting rod. The rod is mounted on an insulated base, helping minimize unwanted electrical conduction through the supporting structure.
When a charged object is brought near a pith ball, electrostatic forces can cause the ball to move. This movement provides a simple method for demonstrating the presence and effects of static electric charge.
The apparatus can also be used to investigate electrostatic attraction and repulsion. When the lightweight balls acquire suitable charges, their relative movement provides a visible demonstration of interactions between charged bodies.
Micro Technologies supplies the Pith Ball Electroscope as a compact and reusable apparatus that can be combined with friction rods, electrostatic materials kits, Van de Graaff generators, and other compatible electrostatic equipment.

FAQs
What is a Pith Ball Electroscope used for?
It is used to observe the presence and effects of electrostatic charge and to demonstrate attraction and repulsion between charged objects.
How many pith balls are provided?
The apparatus consists of a pair of lightweight balls.
How are the balls supported?
The balls are suspended by fine threads from a supporting rod.
Why are lightweight balls used?
Their low mass allows them to respond visibly to relatively small electrostatic forces.
Can it demonstrate electrostatic attraction?
Yes. A charged object can cause a lightweight suspended ball to move toward it under suitable conditions.
Can electrostatic repulsion also be demonstrated?
Yes. When suitable like charges are established, repulsive interaction can be observed.
Does the apparatus require a power supply?
No. It can be used with electrostatically charged objects without requiring its own electrical supply.
Can it be used with friction rods?
Yes. Ebonite, Perspex, polythene and other suitable electrostatic charging rods can be used with the apparatus.
