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. Teachers use it in school physics practicals, college electricity labs and electrical training rooms. It is manufactured by Science Lab Supplies at Plot 448, HSIIDC Industrial Area, Saha, Ambala, India, and supplied factory-direct to schools, colleges, tender contractors and distributors.
Specifications
The model shows a primary coil, a secondary coil and a magnetic core, so students can see where the changing flux of the primary induces a voltage in the secondary. It is meant for a low-voltage AC supply; coil turns, voltage rating, core arrangement and terminals are confirmed on the quotation.

Applications and Experiments for the Demonstration Transformer
Students connect the primary coil to a low-voltage AC source, read the secondary voltage with 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 electricity labs: comparing turns ratio with the voltage ratio.
- ITI electrician and electrical training: identifying primary and secondary windings and core function.
- Explaining flux linkage, laminated core function and transformer losses.
Standard Scope of Supply
The Demonstration Transformer Model is supplied as one teaching unit as described above. Whether connecting leads, a meter, a power supply or a load are packed with it is set out on the quotation; a suitable low-voltage AC source and voltmeter can be quoted as separate lines if your lab needs them.
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). Enquiries go through the contact page or the enquiry cart, while tender documents are handled via the lab tender page.
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.
Who makes the Demonstration Transformer Model?
Science Lab Supplies, a science kit manufacturer in India, makes it. The model comes out of the company's own Ambala factory in Saha, India, and buyers receive quotations straight from the manufacturer with no trading layer in between.
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.
