Using methods based on an integration along magnetic field lines in a given magnetic field, the 1/ν neoclassical transport as well as the variation of the second adiabatic invariant on a magnetic surface are studied for the Wendelstein 7-X (W7-X) standard high-mirror configuration. The analysed quantities are calculated for the magnetic field presented in magnetic coordinates as well as for the vacuum magnetic field. The results obtained for large numbers of magnetic field harmonics are compared to results with a truncated set of harmonics.
