    In Fig. 1, the authors labeled north (Nm) and south (Sm) magnetic poles near north (N) and south (S) geographic pole respectively, which is against the custom within the scientific community. Actually, Nm is next to S and Sm is next to N, which can be found from a textbook (Essentials of college physics, 2006. Raymond A. Serway and Chris Vuille. USA: Cengage Learning. p. 493. ISBN 0-495-10619-4.). This is also explained on the following webpage: http://wtamu.edu/~cbaird/sq/2013/11/15/why-does-a-magnetic-compass-point....
    Although the way shown in this paper is also seen on the Wikipedia webpage (https://en.wikipedia.org/wiki/Earth%27s_magnetic_field), the original figure includes a bar magnet model, which makes it less misleading. I think it is necessary to keep the scientific rigor and follow the common view when illustrating earth’s magnetic field, even if the points in the paper won’t be affected.
