Electric whirl Manufacturer,Supplier and Exporter in India
Product Code : SCL-ES-12906
The Educational Instrument Electric whirl is a physics lab accessory for demonstrating how high-voltage electrostatic charge can produce motion. When connected to a suitable electrostatic machine, charge accumulates near the pointed arms, ionizes nearby air, and creates a reaction force that makes the whirl rotate.
This apparatus is useful for explaining point discharge, corona effect, conservation of momentum, and the conversion of electrostatic effects into visible mechanical motion. It is best used with a compatible static electricity source such as a Van de Graaff generator or Wimshurst machine.

How to Use the Electric whirl
Place the compatible electrostatic generator on a clean, dry, stable laboratory bench.
Mount the Electric whirl securely on the recommended terminal or support point.
Check that the rotating arm is balanced and can move freely without obstruction.
Operate the electrostatic machine gradually under teacher supervision.
Observe the direction and speed of rotation as charge builds at the pointed ends.
Switch off or stop the electrostatic machine before removing the accessory.
Discharge the apparatus safely before touching or storing any part.
Safety note: Use only under trained supervision. Keep hands dry, do not touch charged conductors, and discharge the apparatus before adjustment or storage.
Care & Maintenance
Store the Electric whirl in a dry cabinet to reduce moisture-related charge leakage.
Keep the rotating points clean, dry, and free from dust or corrosion.
Check that the arm rotates freely before each demonstration.
Do not bend the pointed arms or use the apparatus if the mount is loose or damaged.

Frequently Asked Questions
What is an electric whirl apparatus used for?
An electric whirl apparatus is used to demonstrate ion wind, point discharge, charge concentration, and electrostatic reaction force in physics laboratories.
How does an Electric whirl rotate?
An Electric whirl rotates when charge accumulates at its pointed ends and ionizes nearby air. The resulting reaction force produces visible rotation.
Can the Electric whirl be used with a Van de Graaff generator?
Yes, it can be used with a compatible Van de Graaff generator or other suitable electrostatic machine. Final compatibility should be confirmed before purchase.
Is this apparatus suitable for school laboratories?
Yes. The Electric whirl is suitable for school and college laboratories when used under teacher supervision and with proper electrostatic safety handling.
Does the Electric whirl require a power supply?
The Electric whirl itself does not function as a power source. It requires a compatible electrostatic generator or machine to produce the charge needed for rotation.
What should be checked before using the apparatus?
Check that the rotating arm is free, the mounting is secure, the apparatus is dry, and the electrostatic machine is suitable for the demonstration.
