"WebThis phenomenon is called the skin effect. The skin depth is the distance at which the current density drops to 1/e (about 0.368) of the surface density. 86.5% of the heat caused by the passage of current is generated in the skin depth. Equation for calculating the skin depth: where is: [m] skin depth. [Ωm] resistivity. " - Induction heating skin effect
