Product Code : SCL-SK-12136
Demonstration Transformer Model (SKU SCL-SK-12136) is a physics teaching apparatus for showing mutual induction, AC voltage transformation, step-up and step-down action and how a transformer is built. It suits school physics practicals, college electricity labs and electrical training rooms. Science Lab Supplies makes the model in its own Saha, Ambala plant (Plot 448, HSIIDC Industrial Area, India), and schools, colleges, tender contractors and distributors receive it straight from there.
Specifications
The specification table for the transformer model follows. In short, it shows a primary coil, a secondary coil and a magnetic core, so students can see the changing flux of the primary induce a voltage in the secondary; it is meant for a low-voltage AC supply, with coil turns and rating confirmed on the quotation.

Applications and Experiments for the Demonstration Transformer
With the primary coil on a low-voltage AC source, students can read the secondary voltage on a voltmeter or multimeter and relate the result to the turns ratio. The model supports electromagnetic induction and alternating current topics in senior secondary physics, college electricity practicals and electrical trade training.
- Class 12 physics (CBSE/NCERT): electromagnetic induction and the transformer in the alternating current unit.
- B.Sc. and diploma labs: comparing turns ratio with voltage ratio, reading the secondary on a meter such as the Digital Multimeter.
- ITI electrician and electrical training: identifying primary and secondary windings and core function.
- Explaining flux linkage, core function and transformer losses, with the primary fed from a stepped source such as the AC/DC Laboratory Power Supply (AC steps of 1–15 V) once checked against the model’s rating.
Standard Scope of Supply
The Demonstration Transformer Model is supplied as one teaching unit as described above. Which items are packed with it, such as connecting leads, a meter, a power supply or a load, is set out on the quotation, and a low-voltage AC source and voltmeter can be priced as separate lines.
Packing, MOQ and Lead Time
Quote requests can be for one model for a teacher’s demonstration or for a full practical batch. The quotation lists packing, delivery time and price for exactly that quantity, and STEM science kits in India from the same range can be added so the physics lab is covered in one order.
As a registered exporter with an Importer-Exporter Code, Science Lab Supplies can ship to buyers in South Africa, Qatar, Sri Lanka, Vietnam, Malaysia and Peru. The business is registered under Udyam as a manufacturing enterprise (UDYAM-HR-01-0014546) and for GST (GSTIN 06ADEPJ0574F2ZU). To price the model for an induction practical, write via the contact page, use the enquiry cart, or consult the lab tender page for tenders.
Frequently Asked Questions
What principle does the transformer model demonstrate?
Electromagnetic induction: a changing current in the primary coil produces a changing magnetic flux in the core, which induces a voltage in the secondary coil in proportion to its turns.
Can it show both step-up and step-down action?
Yes, where the coil set offered allows different turns ratios. The coil combinations and turns for your unit are confirmed on the quotation, so you can check them against the practical you plan to run.
Who makes the Demonstration Transformer Model?
The transformer model is produced in Science Lab Supplies’ own factory at Saha, Ambala, India, so the company is its manufacturer, not a reseller, and every quotation for it comes straight from that factory.
Can it be connected to mains electricity?
No, not unless the unit is specifically rated for it. Use a low-voltage AC supply under teacher supervision, switch off before changing coils or leads, and stop if coils overheat.
