Influence Machine

Product Code : SCL-EI-10649

The Influence Machine is a physics laboratory electrostatics apparatus manufactured and exported by Lab Glassware Manufacturer, based in Ambala, Haryana, India, in continuous operation since 1982. This apparatus is supplied to school and university physics laboratories across Western Europe, including Germany, the Netherlands, Belgium, and Luxembourg, supporting classroom demonstrations of electrostatic induction, charge separation, and spark discharge.

Quick answer: The Influence Machine generates static electric charge by rotating insulating discs so that metal sectors, collecting combs, and discharge electrodes build up opposite charges that release as a visible spark, demonstrating electrostatic induction, attraction, repulsion, and high-voltage effects. Many classroom influence machines are Wimshurst-type and hand-cranked, but the exact construction, spark gap, output voltage, and Leyden jar inclusion should be confirmed with Lab Glassware Manufacturer before publication or tender submission.

Key Features

• Electrostatics demonstration: shows static charge generation, induction, and discharge effects.
• Classroom visual impact: students observe sparks, attraction, repulsion, and charge behaviour.
• Physics lab relevance: supports electrostatics chapters in school and college physics curricula.
• Manual operation: operated by hand crank where the supplied model supports that design.
• Reusable teaching apparatus: suitable for supervised repeated demonstrations in physics labs.
• Specification-dependent safety: spark gap, insulation, and capacitor/Leyden jar details must be verified.

What's Included

• 1 x Influence Machine
• Discharge electrodes, Leyden jars, crank handle, base, instruction sheet, storage packaging, or certificate, only if specified in the order

Applications / Uses

• Demonstrating static electricity in physics laboratories.
• Showing electrostatic induction and charge separation.
• Producing visible spark discharge for classroom observation.
• Explaining attraction and repulsion between charged bodies.
• Introducing high-voltage electrostatic concepts safely under supervision.
• Supporting school, college, STEM, and science exhibition demonstrations.

How to Use the Influence Machine

1. Place the Influence Machine on a dry, stable, non-conductive laboratory bench.
2. Inspect the discs, belts, brushes, collectors, electrodes, base, and jars before use.
3. Keep the discharge electrodes separated according to the experiment requirement.
4. Rotate the crank slowly and steadily to build electrostatic charge.
5. Observe spark discharge, attraction, or repulsion effects as directed by the teacher.
6. Stop cranking before adjusting electrodes or touching any part of the apparatus.
7. Discharge stored charge safely using the recommended procedure before storage.

Safety note: Use only under teacher supervision. Keep the apparatus away from pacemakers, sensitive electronics, flammable vapours, and wet surfaces. Do not touch electrodes during operation, and discharge the machine after every demonstration.

Care & Maintenance

• Store the machine in a dry, dust-free cabinet to protect insulation performance.
• Clean discs gently with a soft dry cloth; do not use abrasive cleaners.
• Check belts, brushes, electrodes, and jars before repeated classroom use.
• Do not operate if discs are cracked, terminals are loose, or insulation is damaged.

Part of a Complete Electrostatics Teaching Sequence

The Influence Machine gives a hand-cranked, higher-voltage electrostatics demonstration for classrooms that have already introduced the basics with simpler apparatus. Schools building a fuller electrostatics sequence often start with the Electrostatics Starter Kit and friction-based charging demonstrations such as the Friction Bar Glass and Friction Bar (Hard Rubber), before introducing the Influence Machine for induction and spark-discharge effects at a more advanced level.

Frequently Asked Questions

What is an Influence Machine used for?
An Influence Machine is used to generate static electric charge and demonstrate electrostatic induction, spark discharge, attraction, repulsion, and high-voltage electrostatic effects.

Is an Influence Machine the same as a Wimshurst machine?
Many school influence machines are Wimshurst-type electrostatic machines. Confirm the exact design before listing the product as a Wimshurst machine.

Does it require an external power supply?
Most classroom influence machines are manually operated by a crank, but the final operating method must be confirmed from the supplied model.

What spark gap does it produce?
The spark gap or output is not confirmed. Add spark distance or voltage details only after checking the product datasheet or tested specification.

Can it be used in school physics labs?
Yes. It is suitable for supervised school and college electrostatics demonstrations when safety instructions are followed.

Does it include Leyden jars?
Leyden jar or capacitor inclusion is not confirmed. List charge-storage components only after verifying the final supplied configuration.
