Linguistic Origin & Historical Etymology

Derived from the combination of 'magnetic', originating from the Greek 'magnes lithos' (lodestone from Magnesia), and 'anomaly', stemming from the Greek 'anomalia' meaning inequality or irregularity. The compound term developed in the mid-20th century with the advent of airborne and marine geomagnetism during geophysical mapping of the Earth's crust.
