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. Science Lab Supplies builds the machine, plates, uprights and Leyden jars included, at its Plot 448, HSIIDC Industrial Area works in Saha, Ambala, and manufactures to order for schools, colleges, tender contractors and distributors.
Specifications
The table gives the Wimshurst plates, jars and spark figures one row each. In short, two 200 mm plates of heavy, high-resistance plastic with aluminium sheet sectors are belt-driven in opposite directions between two rigid uprights, and two Leyden jars of glass and aluminium foil store the charge on a polished wooden base.

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. It can be used to show high-voltage discharge, the action of capacitors and the link between charge and lightning, fitting 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, extended with the 21-experiment Electricity EL2+ Electrostatics, Magnetostatics, Induction, Lorentz Force Set.
- Class 12 electrostatic potential and capacitance: the Leyden jar as an early capacitor, followed by a measured run on the Capacitor (Charging and Discharging) board.
- 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 items, such as friction rods or a discharge sphere, can be added as lines 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. An electrostatics order can be raised with a note on the contact page or a shortlist in the enquiry cart, and the lab tender page outlines how tender-based purchases are handled.
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.
How should the machine be used in class?
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 the machine or moving it.
Does Science Lab Supplies manufacture the machine?
Yes. From the sectored plates to the polished base, the Wimshurst machine is put together in the company’s own Saha, Ambala factory, so the maker itself prepares your quote with no trader in between.
