The distribution of current over the entire … spheres of influence examplesspheres of hydrationCause 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.
