  • Primary Secondary Coil set is used to demonstrate induction of electricity in one coil while there is a change of voltage in the other coil. The iron core is used to show that such induction increases while the iron core is present.
  • Use the promary and secondary coil set to demonstrate how a transformer works.
  • The promary and secondary coil set as well as the iron rod can be inserted in each other to form a transformer.

    • Primary and Secondary Coil Set (Made in INDIA)

    Product Description

    For studying electromagnetic induction, ferromagnetism and principles of a transformer. Consists of two coils wound with enamelled copper wire over heavy plastic spools fitting one within the other. The inner coil has 250 turns of heavy wire and the outer coil has 1250 turns of fine wires. Square supports of thick insulating material are used as vertical or horizontal mount. Both coils are equipped with binding posts and a soft iron core for induction studies. To increase the voltage, use the inner coil as the primary coil and the outer coil as secondary coil. Switch them around to reduce the voltage and increase the current. The Iron core in this model may come with a wooden handle.
