Variable Inductance Coil Manufacturer,Supplier and Exporter in India

Product Code : SCL-EI-10735

The variable inductance coil is a physics laboratory apparatus used for changing inductance in AC circuit, resonance, electromagnetism and inductive reactance experiments. It is designed for school physics labs, college laboratories, STEM classrooms and electronics training rooms where students need to observe how coil geometry or core position affects circuit behaviour.

Product Description

The Coil of Variable Inductance allows students to vary the effective inductance in a circuit and study the resulting change in current, voltage, impedance, phase relationship and resonance condition. It is useful for experiments where a fixed coil does not provide enough adjustment for comparison-based learning.

This apparatus belongs in the Electronic Instruments category and supports lessons in electromagnetism, alternating current, transformer principles and tuned circuits. It can be used with compatible meters, power supplies and circuit boards, including related products such as the Coil With 400 Turns and Student Electromagnetism Kit.

Key Features

• Adjustable inductance: Enables practical study of changing coil inductance in electrical circuits.
• AC circuit learning: Supports experiments on impedance, inductive reactance and phase difference.
• Electromagnetism demonstration: Helps students connect magnetic field behaviour with current-carrying coils.
• Useful for resonance work: Can support LC circuit and frequency-response activities when paired with compatible capacitors and meters.
• Laboratory teaching format: Suitable for supervised school, college and STEM laboratory use.
• Capacity by electrical range: Capacity is defined by inductance range, not by liquid volume.
• Specification-safe listing: Inductance range, current rating and core material must be confirmed before publication.

How to Use the Coil of Variable Inductance

1. Place the coil on a dry, stable and insulated laboratory bench.
2. Confirm the inductance range, current rating, voltage rating and terminal type before connection.
3. Connect the coil into the approved low-voltage AC or experimental circuit.
4. Set the coil to its starting inductance position according to the experiment worksheet.
5. Switch on the supply and record current, voltage or frequency response.
6. Adjust the inductance slowly and observe the change in readings.
7. Switch off the supply before changing the circuit, meter range or coil connections.

Safety note: Use only within the confirmed voltage and current rating. Do not connect the coil directly to mains electricity, short the terminals or operate it if the winding, insulation or terminals are damaged.

Care & Maintenance

• Keep the coil dry and away from moisture, chemicals and metal filings.
• Do not force the adjustable core, slider or tapping mechanism.
• Store the coil in protective packing to prevent winding and terminal damage.
• Check insulation, terminals and abnormal heating before repeated student use.

Frequently Asked Questions

What is a variable inductance coil used for?

A variable inductance coil is used to change inductance in a circuit and observe the effect on current, voltage, impedance, phase and resonance behaviour.

How does the Coil of Variable Inductance work?

It changes the effective inductance by altering the coil arrangement, core position or winding connection, depending on the final design. The exact adjustment method must be confirmed.

Is it suitable for school physics labs?

Yes. It is suitable for supervised school and college physics laboratories when used with compatible low-voltage power supplies and meters.

Can it be used in resonance experiments?

Yes, it can support LC resonance experiments when used with a compatible capacitor, signal source and measuring instrument within confirmed ratings.

What specifications should be confirmed before ordering?

Confirm inductance range, adjustment method, wire material, current rating, voltage rating, core material, terminal type, dimensions and included accessories.

Can it be connected to mains electricity?

No. It should not be connected directly to mains electricity unless the final verified datasheet specifically permits that use with proper safety protection.
