Modelling of Inductive Effects in Thin Wire Coils

In conducting media, inductive effects give rise to eddy currents that produce skin effect and proximity effect. In thin wire coils in which the inductive effects are present the current density is forced to remain constant in the coil if the skin depth is larger than the characteristic size of the wire. This paper presents a homogenization technique based on the finite element method, to take into account thin wire coils in two-dimensional dynamic magnetic field computations.
