Weekly Progress At first, I would find out the data of coil. But I changed to use inductive Heating instead of Coil. So I search the data of Inductive Heating as the below. In a basic induction heating setup shown at right, a solid state RF power supply sends an AC current through an inductor (often a copper coil), and the part to be heated (the workpiece) is placed inside the inductor. The inductor serves as the transformer primary and the part to be heated becomes a short circuit secondary. When a metal part is placed within the inductor and enters the magnetic field, circulating eddy currents are induced within the part.

Figure 1.

As shown in diagram, these eddy currents flow against the electrical resistivity of the metal, generating precise and localized heat without any direct contact between the part and the inductor. This heating occurs with both magnetic and non-magnetic parts, and is often referred to as the "Joule effect", referring to Joule's first law – a scientific formula expressing the relationship between heat produced by electrical current passed through a conductor.

Engineering Analysis

Strong Point - Inductive heating give the heat more than coil. - It is saver energies than coil.

Week Point - It conducts the heat only metal.

Next Week Job - I will research the data for other part.
