Numerical Modelling of Eddy Currents

Numerical methods for solving low frequency electromagnetic field problems--many of which refer to eddy currents appearing in various electromagnetic devices--have been developed and utilized with increasing success in recent years. Originally such problems were tackled by analytical solutions
limited to simple geometries and linear materials. In practice, however, all electromagnetic devices have complex boundaries, include non-linear materials, and may be treated exclusively by numerical methods. This book provides a systematic, mathematical simulation of existing methods and discusses
the discretization of relevant equations. Methods described include finite difference, finite sums, finite element, boundary element, and some variants. Physical connotations of methods and problems are also given. Written by top experts in the field, this book fills the need among professional
electrical engineers and graduate students for both a theoretical and practical approach to this important topic.

Summary

Eddy currents appear in electromagnetic devices (e.g. the cores of transformers or rotors in electric motors) whenever a magnetic field varies through a conductor. Very often they are undesirable representing a power loss. The prediction of eddy currents is therefore of great practical importance. This book looks at numerical modelling methods for the prediction of eddy currents.

Additional text

a pleasure to welcome a new book on numerical modelling by one of the original Greek authors and a colleague from Poland ... There is in fact a gem of insight on almost every page ... Throughout the text the references are very helpful and, in summary, the authors are to be cogratulated in producing an excellent book. As usual the Clarendon Press have produced a text of high quality.
