The very first computational and most referred in the literature algorithm of Talwani and Heirtzler (1964) for calculating of the magnetic anomaly caused by two-dimensional irregular shape subsurface structure has particular fundamental and educational significance in geophysics theory. We re-derive this algorithm from first principles and discuss previous derivation omissions. Our resulting solution differs from the original publication. Based on our new solution we present the two-dimensional forward magnetic modeling software and associated tutorials which are available for download from the website www.ualberta.ca/similar to vadim/software.htm. Additionally, we include the computation of the remnant magnetization which can be found using already published apparent polar wonder paths.
