A high-efficiency post-processing method for computing the magnetic flux in coils is discussed and applied to magnetodynamic problem analysis. The method separates the contribution of magnetic flux in a coil into three parts, respectively generated by source coils, the magnetization of magnetic region and eddy currents in conductive region. The computation of the three components of magnetic flux in coil can be transformed to coil-region-independent integrals, which can help to reduce the mesh

The method is well adapted to any numerical techniques, such as the finite element and volume integral methods. A typical electromagnetic shielding problem is used to validate the performance of the post-processing magnetic flux computational method at low frequency application.
