what is the skin effect?

the skin effect is a phenomenon in which alternating current flows unevenly relative to the cross-section of a conductive element, such as a wire. current density is highest near the surface of a conductor and decreases exponentially with distance from the surface.

"skin depth" "current density" is the point at which the current density at the surface of a body reaches approximately 37% of its value. calculating skin depth requires the frequency of the ac signal and the resistivity and relative permeability of the conductive material. to use this calculator, simply select the material type and enter the signal frequency. the resistivity and relative permeability of the selected material are automatically given.
