Double electric pendulum Manufacturer,Supplier and Exporter in India
Product Code : SCL-ES-12900
The Educational Instrument Double electric pendulum helps students observe how charged objects interact with suspended lightweight bodies. When a charged rod is brought near the pendulum bodies, students can see attraction, separation, repulsion, or discharge effects depending on the charge condition and contact method.
This apparatus is useful in electrostatics lessons because it gives a simple visual response without complex measuring instruments. It can be used with friction rods, silk cloth, an electroscope, or other approved electrostatics accessories. Exact pendulum material, stand material, thread type, and dimensions should be confirmed before final publishing.
Key Features

How to Use the Double Electric Pendulum
Place the double electric pendulum on a stable, dry, level surface.
Check that both suspended pendulum bodies hang freely without touching the stand or base.
Charge a suitable friction rod using an approved rubbing cloth.
Bring the charged rod close to one pendulum body without touching it and observe attraction.
Touch the charged rod to a pendulum body to transfer charge by contact.
Observe whether the two pendulum bodies attract, separate, or repel each other.
Discharge the pendulum bodies safely before repeating the experiment.
Safety note: Use this apparatus only for low-energy static electricity demonstrations. Keep it away from high-voltage sources, flames, solvents, moisture, and delicate electronic devices.
Care & Maintenance
Store the apparatus in a dry cabinet to reduce moisture-related charge leakage.
Handle the suspended pendulum bodies gently to avoid damaging the thread or support.
Remove dust with a clean, dry, soft cloth after use.
Do not bend the stand, pull the suspension threads, or use chemical cleaners unless material compatibility is confirmed.

Frequently Asked Questions
What is a double electric pendulum used for?
A double electric pendulum is used to demonstrate electrostatic attraction, repulsion, charge transfer, and induction using two suspended lightweight bodies.
How does a double electric pendulum show repulsion?
When both pendulum bodies acquire similar charges, they move apart because like charges repel. The visible separation helps students observe electrostatic repulsion directly.
Can this apparatus be used with friction rods?
Yes. A double electric pendulum is commonly used with charged friction rods to demonstrate attraction, contact charging, and repulsion.
Is the double electric pendulum suitable for school physics labs?
Yes. It is suitable for supervised school physics laboratories, college practical classes, STEM labs, and teacher-led science demonstrations.
What material is the pendulum made from?
The exact material should be confirmed before publishing. The pendulum body, suspension thread, stand, and base material may vary by model.
Why should the apparatus be kept dry?
Moisture allows electrostatic charge to dissipate quickly. Keeping the apparatus dry improves the visibility and repeatability of the experiment.
