Induction Coil Manufacturer,Supplier and Exporter in India
Product Code : EL-SLE-4616
Jlab Export is a leading Induction Coil Manufacturer,and suppliers in India
Induction Coil (code EL-SLE-4616) is a physics apparatus that produces a high voltage from a low-voltage direct-current supply, used for electrical experiments such as demonstrating mutual induction and making sparks jump an air gap in school and college labs. It is offered in spark lengths of 5 mm, 10 mm, 20 mm and 25 mm, so the output can be matched to the experiment. It is made by Jain Laboratory Instruments Pvt Ltd (JLab) at its works in Ambala, India.

How Does It Compare with Other JLab Induction Coils?
| Model | Listed details |
|---|---|
| This induction coil (EL-SLE-4616) | High voltage from low-voltage DC; spark lengths 5, 10, 20 and 25 mm |
| Induction Coil (teak wood case) | Teak wood case; platinum make-and-break points, one adjustable; reversing and on/off switches; works on 6–12 V DC; spark lengths from 5 mm up to 150 mm |
| Student Induction Coil | Teakwood base with graduated scale; interrupter working directly off the iron core; heavy-duty contacts |
| Induction Coil Demonstration | Two coils on separate bobbins with a soft iron core, for showing how induced voltages arise |
Choose this coil for spark and high-voltage demonstrations within a 25 mm spark length. The teak-case model offers much longer sparks, while the demonstration coil set is meant for showing induction itself rather than producing high voltage.
What Is the Induction Coil Used For?
An induction coil works by mutual induction. In the usual design, a primary winding of a few turns of thick wire and a secondary winding of many turns of fine wire share a soft-iron core; an interrupter repeatedly makes and breaks the direct current in the primary, and each time the current is cut the magnetic field collapses quickly and induces a much higher voltage in the secondary — enough to drive a spark across the gap between its terminals. The spark-length rating is the longest air gap the coil can spark across, so a longer rating means a higher output voltage. Teachers use it for class 12 physics on electromagnetic induction, for class 11 chemistry demonstrations of discharge in gases and cathode rays, and for college electrical labs.
The output is high voltage: the coil should be operated by the teacher, students should stay clear of the secondary terminals, the supply should be switched off before connections are changed, and any discharge tube connected to it should be used only as its own instructions allow.
What to Specify When Ordering
- Spark length — 5 mm, 10 mm, 20 mm or 25 mm, matched to the apparatus the coil will drive.
- Supply — tell JLab the DC source you will use (battery or bench supply) so the coil's supply rating can be confirmed.
- Quantity — the minimum order is 10 units; mixed spark lengths can be listed in one enquiry.
- Delivery details — destination, delivery terms and any packing or tender requirements.
Frequently Asked Questions
What does an induction coil do?
It turns a low-voltage direct current into a high voltage, which is used in electrical experiments such as producing sparks and showing mutual induction.
Which spark lengths are available?
Four: 5 mm, 10 mm, 20 mm and 25 mm. A longer spark length corresponds to a higher output voltage.
How do I choose the spark length?
Match it to the work. Check the voltage needed by any discharge tube or apparatus you plan to drive, and choose a rating that covers it; for simple spark and induction demonstrations, a shorter rating is often enough.
What power supply does it need?
A low-voltage DC supply. The exact voltage and current are not given in this listing, so ask JLab to confirm them for the spark length you order.
Is the induction coil safe for students to use?
It produces high voltage, so it should be a teacher-operated demonstration: keep students away from the secondary terminals and switch off before touching any connection.
What should an export quotation request include?
The spark lengths and quantities, the destination country and port or city, delivery terms such as FOB or CIF, packing or labelling needs, and any tender reference.
Who manufactures this induction coil?
Jain Laboratory Instruments Pvt Ltd (JLab) makes it at its works in Ambala, Haryana, India, and quotes for it directly.
OEM Manufacturer
JLab is the trading name of Jain Laboratory Instruments Pvt Ltd, a physics and electrical laboratory equipment manufacturer in India, incorporated in 2017 and based on Hargolal Road, Ambala, Haryana. The induction coil is wound and assembled at JLab's own works rather than bought from a trader, so schools, colleges, dealers and importers buy factory-direct, each coil is visually inspected before dispatch, and repeat orders are handled by the manufacturer. The company holds GSTIN 06AADCJ9848D1ZE and Legal Entity Identifier 549300DTGS77DGYD6N03. JLab exports worldwide and ships to buyers in every region — Angola in Central Africa, Brunei in Southeast Asia, Afghanistan in South Asia, Eswatini in Southern Africa and Colombia in South America among them. Tender information is on the JLab lab tenders page.
