500 Watt Induction Heater Circuit

Last updated on 12 July 2025 by Admin-Lavi Leave a Comment

This post is about 500 Watt Induction Heater Circuit Coil makes strong magnetic field and it changes very fast. When metal connects inside a coil then the metal becomes hot. This happen because of eddy current which goes round and round inside metal. Metal also heat up little more from its own property but that […]
