Induction heaters are devices that generate high frequency electromagnetic fields to induce heat in conductive materials. Some common synonyms for induction heater include induction furnace, electromagnetic heater, and induction heating system. Other terms that can be used to describe these devices include RF heaters, induction heating machines, and solid state heaters. Some manufacturers also refer to their induction heaters as power supplies, transformers, or magnetic generators. Regardless of the specific terminology used, the fundamental principle behind induction heaters remains the same: the use of magnetic fields to rapidly heat up metals and other conductive materials without direct contact, making them an efficient and effective tool in various industrial applications.
