Quick Answer: The Electrical Transformer Model is a physics apparatus that demonstrates how an AC transformer works, using coils on a laminated core to show electromagnetic induction, mutual induction and voltage transformation.
Last updated: October 2026
Key Features
Alternating current in the primary coil produces a changing magnetic field in the iron core.
The changing flux links the secondary coil and induces a voltage.
Step-up and step-down demonstrations are possible when compatible coils are used.
Relates turns ratio to induced voltage.
Open format lets students see how a transformer is built.
About This Product
Teachers use the model to explain mutual induction between primary and secondary coils and magnetic flux linkage through a laminated iron core. Using compatible coils, students compare step-up and step-down transformation and study the effect of the turns ratio on induced voltage. It supports electromagnetism practicals in school physics labs and college practical rooms. Besides buyers across India, the Electrical Transformer Model can be exported to institutions in São Tomé and Príncipe, Bangladesh, Panama, Mexico and Guinea.
Frequently Asked Questions
Q1. How does the model show step-up and step-down action? Coils with different numbers of turns are used as primary and secondary. Comparing the induced voltage for different turns ratios shows step-up or step-down transformation.
