Fig. 5. A comparison between the finite element result and the 1D semi-analytical solution for the secondary magnetic field with a frequency of 0.5 Hz on the seafloor. The upper panel shows a comparison for the x component of secondary magnetic field at = −y 50 m; the middle panel shows a comparison for the y component of secondary magnetic field at y¼0; the lower panel shows a comparison for the z component of secondary magnetic field at = −y 50 m.
