Quick Answer: The Induction Coil Apparatus demonstrates electromagnetic induction, showing how a changing current in a primary coil induces a higher voltage in a secondary coil.
Last updated: October 2026
Key Features
Primary and secondary coil action
Shows induced voltage from changing magnetic flux
Explains transformer action and voltage step-up
Can support spark-gap demonstrations, subject to the final model rating
About This Product
On a dry, insulated surface, the input and output terminals and switching arrangement are identified and the rated supply is connected. The supply is switched on briefly while students observe the induced output, then switched off before any change. Because induction coils may produce high voltage, the apparatus is used only under teacher supervision. It supports lessons on Faraday’s and Lenz’s laws. Export supply of the Induction Coil Apparatus can be arranged to laboratories and schools in Estonia, Vanuatu, Senegal, Maldives, Mauritania and Luxembourg.
