Electric Whirl

Product Code : ILS-E-11769

Indian Lab Suppliers supplies the Electric Whirl (Product ID: 11769), part of the Electrostatics range under Electricity and Magnetism. It is a pointed-spoke rotor that spins when placed near a charged Van de Graaff dome.

Quick Answer

Charge leaving the pointed spokes ionises the surrounding air; the ions are repelled, and the reaction force spins the whirl away from the points. Brought near a Van de Graaff dome it spins quickly, and even if started the other way it stops and reverses.

Where This Is Used

Physics teachers use it to show corona discharge and action-reaction forces with the Deluxe Van de Graaff Generator (Product ID: 11760). Browse the full Electrostatics range or the wider Electricity and Magnetism catalogue.
