Hi. I'm trying to understand why smaller skin depths are better for induction heating. Skin effect means that the highest the frequency is, the thinest the skin depth is (or the depth is simply smaller because of the material). That means the section of the workpiece with electric current in it is smaller, and according to R=ρ*L/S (ρ - electrical resistivity, L - length, S - section area) the resistance is higher, thus heating more. But if the resistance is higher, the current decreases so that the power remains the same, right? So what makes the difference when the skin depth is changed?
