Wimshurst Machine
Product Code : EL-PLE-14951
Eduscope India is a leading Wimshurst Machine
The Wimshurst Machine from Eduscope India is a classic hand-cranked electrostatic (friction/induction) generator, widely used in physics classrooms and laboratories to demonstrate static electricity and high-voltage phenomena, a staple instrument within our Physics Lab Equipment range. Quick Answer: this Wimshurst Machine is a hand-cranked electrostatic generator producing up to 75,000V with sparks up to 12cm - dependable physics lab equipment India schools use for static electricity demonstrations.
Construction and Specifications
This machine offers students a hands-on way to observe charge build-up and controlled sparking in a safe, classroom-friendly format - practical laboratory equipment school India physics departments rely on. Built around a hand-turned crank mechanism, the machine generates charge through friction and induction as its disc rotates, building up static electricity that is released as a visible spark. The disc diameter measures up to 31 cm, and the unit is rated for a spark length of up to 12 cm. Being manually operated, the machine requires no external power source, making it convenient for repeated classroom and laboratory demonstrations. Electrically, the machine develops a maximum potential of approximately 75,000 V (75 kV), with a short-circuit current of approximately 7 microamperes. Under typical dry-air conditions, the maximum spark distance achieved is approximately 75 mm - a separate, real-world figure distinct from the machine's rated spark-length capacity of up to 12 cm.
