In this video we demonstrate "contactless" heating with the Inductor. The F-Core helps to focus the induction field and is most efficient when the device is in direct contact with the core. That said the field does propagate out and interact with objects, not in direct contact as shown in the video. This demo/method is not best practice for efficiency = requires longer heating times. It's just a fun demonstration that this type of heating is possible.
Induction works by creating a continuously oscillating electromagnetic field that induces current into the target object. This causes the object to heat up. One of the unique features of our technology is the Inductor is designed to induce a lot of current in a short amount of time and have good material penetration. Where other induction units are good at surface heating we have designed our unit to heat the target more deeply and have a farther "reach".
