Spark inductor (Rühmkorff coil) Manufacturer,Supplier and Exporter in India

Product Code : SCL-EI-10688

The spark inductor (Rühmkorff coil) is a physics laboratory apparatus used for demonstrating electromagnetic induction, high-voltage pulse generation, spark discharge, and transformer action in school and college laboratories. It helps students observe how a low-voltage input can produce a visible high-voltage spark under controlled teacher supervision.

Product Description

The Spark Inductor (Rühmkorff Coil) from Lab Glassware Manufacturer is designed for classroom demonstrations in electricity and magnetism. A Rühmkorff coil is commonly used to show the principle of induction coils, make-and-break current action, secondary voltage generation, and spark discharge between terminals.

This apparatus belongs to the physics lab equipment category and is intended for supervised educational use. Input voltage, spark length, coil winding, interrupter type, terminal design, and enclosure details must be confirmed before final publishing or quotation because these specifications affect performance and safety.

Key Features

• Induction coil demonstration: Shows how changing current in a primary coil can induce a higher voltage in a secondary coil.
• Visible spark output: Helps students observe spark discharge in a controlled laboratory setting.
• Electromagnetism teaching aid: Supports lessons on induction, transformers, magnetic flux, and voltage step-up action.
• Useful for practical physics: Suitable for teacher-led demonstrations in schools, colleges, and STEM laboratories.
• Compatible with lab instruments: Can be used with approved electronic instruments and low-voltage power sources where rated.
• Reusable classroom apparatus: Designed for repeated demonstrations when operated within confirmed ratings.
• Safety-focused handling: Requires trained supervision because the secondary output may produce high voltage.

How to Use the Spark Inductor (Rühmkorff Coil)

1. Place the spark inductor on a dry, stable, non-conductive laboratory bench.
2. Inspect the coil, terminals, leads, and spark gap before connecting any power source.
3. Connect only the rated low-voltage input supply specified for the model.
4. Adjust the spark gap gradually if adjustable terminals are provided.
5. Switch on the supply briefly and observe the spark discharge from a safe distance.
6. Switch off the supply before changing connections, touching terminals, or storing the unit.

Safety note: A spark inductor can generate high voltage at the output. Do not touch the terminals during operation, do not connect it to mains electricity unless specifically rated, and use suitable safety protective wears during supervised demonstrations.

Care & Maintenance

• Keep the coil dry and free from dust, moisture, and conductive contamination.
• Store the apparatus in a dry cabinet after the unit is fully switched off and discharged.
• Do not operate the coil continuously beyond the confirmed duty cycle.
• Replace damaged leads, cracked insulation, or loose terminals before further use.
