- Abstract:
- In this work, efficient techniques for the computation of the low frequency magnetic field due to the electrical circuit in buildings or industrial environment are discussed. Existing models used to compute the magnetic field caused by power lines are recalled at first. Then, an algorithm for the fast evaluation of the magnetic field due to electrical wires is proposed. It is based on the partitioning of the various sources into simpler magnetic sources: for each elementary magnetic source, some closed-form formulae are provided and combination rules are suggested in order to provide the calculation of the magnetic field from the segments associated to the elementary sources themselves.
The algorithm has been validated by comparing the results to the ones provided by well assessed computation method. It is shown that the computational speed of the proposed technique is approximately 200 times faster than the direct application of the Laplace equation. - Download:
