Did you know?
WebSkin Effect results from circulating eddy currents, arising from a changing B field, cancelling the current flow in the center of a conductor and reinforcing it in the skin. This reduces the effective cross sectional area increasing wire resistance and losses. Using the right hand rule (thumb in direction of current and fingers will follow the ...

Cause of skin effect. A current I flowing through a conductor induces a magnetic field H. If the current increases, as in this figure, the resulting increase in H induces circulating eddy currents I W which partially cancel the current flow in the center and reinforce it near the skin. See more In electromagnetism, skin effect is the tendency of an alternating electric current (AC) to become distributed within a conductor such that the current density is largest near the surface of the conductor and decreases … See more The AC current density J in a conductor decreases exponentially from its value at the surface JS according to the depth d from the surface, as follows: $${\displaystyle J=J_{\mathrm {S} }\,e^{-{(1+j)d/\delta }}}$$ where See more The internal impedance per unit length of a segment of round wire is given by: $${\displaystyle \mathbf {Z} _{int}={\frac {k\rho }{2\pi R}}{\frac {J_{0}(kR)}{J_{1}(kR)}}}$$ This impedance is a complex quantity corresponding to a … See more A type of cable called litz wire (from the German Litzendraht, braided wire) is used to mitigate skin effect for frequencies of a few kilohertz to about one megahertz. It consists of a … See more Conductors, typically in the form of wires, may be used to transmit electrical energy or signals using an alternating current flowing through that conductor. The charge carriers constituting that current, usually electrons, are driven by an electric field due to the … See more When skin depth is not small with respect to the radius of the wire, current density may be described in terms of Bessel functions. The current density inside round wire away from the influences of other fields, as function of distance from the axis is given by: See more In a good conductor, skin depth is proportional to square root of the resistivity.
