Wimshurst Machine
Product Code : LSK-PL-10343
Wimshurst Machine (SKU LSK-PL-10343) is an electrostatic influence machine that builds up charge quickly and discharges it at regular intervals, giving sparks of up to 50 mm in air under correct conditions. It needs no electrical power, which makes it a simple way to demonstrate electrostatics in school and college physics. The machine is a Science Lab Supplies product, manufactured at the company’s Plot 448, HSIIDC Industrial Area site in Saha, Ambala and supplied direct to schools, colleges, tender contractors and distributors.
Specifications
Two 200 mm plates of heavy, high-resistance plastic carrying aluminium sheet sectors are held in two rigid uprights and belt-driven in opposite directions. Two Leyden jars made from glass and aluminium foil store the charge, and the whole machine sits on a polished wooden base for easy use and transport.

Applications and Experiments for the Wimshurst Machine
The machine separates charge by induction on the counter-rotating plates, stores it in the Leyden jars and releases it as a visible spark. Teachers use it to show high-voltage discharge, the action of capacitors and the link between charge and lightning, so it is a natural fit for an electricity and magnetism lab kit for schools.
- Middle-school science: static electricity, sparks and lightning.
- NCERT Class 12 physics, electric charges and fields: charging by induction.
- Class 12 electrostatic potential and capacitance: the Leyden jar as an early capacitor.
- B.Sc. electrostatics demonstrations, run under supervision because of the high-voltage sparks.
Standard Scope of Supply
Each machine is supplied on its polished wooden base, with the two 200 mm sectored plates in their uprights, the drive belt arrangement and the two glass and aluminium-foil Leyden jars. Further electrostatics accessories are separate and can be listed on the quotation.
Packing, MOQ and Lead Time
One machine for a demonstration bench or several for a group of schools can be priced. Your quotation sets out packing, delivery time and price for the quantity you request, and friction rods or other electrostatics items can join the same quotation.
Because it holds an Importer-Exporter Code as a registered exporter, Science Lab Supplies is able to ship to buyers in Ethiopia, Tanzania, Uganda, the UAE, Saudi Arabia and Oman. Please send enquiries through our contact page or enquiry cart; the lab tender page covers institutional buying.
Frequently Asked Questions
How long a spark does the Wimshurst Machine give?
Under correct conditions the spark travels up to 50 mm in air between the electrodes. The unit generates charge quickly and then discharges at regular intervals, so a class sees a steady series of sparks.
Does it need mains power?
No electrical power is required. The belt-driven plates, turning in opposite directions, separate the charge themselves, so the machine can be used in any classroom and moved easily on its wooden base.
Is it safe for classroom use?
The discharge is high voltage, so use it under supervision, keep hands clear of the electrodes when charged, and discharge the Leyden jars before handling.
Does Science Lab Supplies manufacture the machine?
Yes. The Wimshurst machine is assembled in the company’s own Saha, Ambala factory, so there is no trader between you and the maker issuing the quote.
