Comparison under three conditions: FEM, external field coils, and measurement values! Analysis with the coils moved was also conducted.
We will introduce the analysis results when using coils and external field coils with the finite element method (FEM) for the same analysis target.
We adopted "Team Workshop Problem 7," which involves placing a coil on a perforated conductor. Since this problem has measurement values, we compared the results under three conditions: FEM, external field coil, and measurement values, and we also conducted analyses with the coil moved.
In the results of the external field and FEM, the graphs overlapped, and the comparison with the measurement values was also favorable.
