Abstract
It is demonstrated mathematically that the length of the geomagnetic induction vector in the so-called S-interval at any observation site on the surface gives the horizontal derivative of the natural logarithm of the depth below the given site, and not simply the depth as it had been assumed by Ádám and Koppán (2004).
