Together with Gauss and Wilhelm Eduard Weber, Goldschmidt published in 1840 "Atlas des Erdmagnetismus: nach den Elementen der Theorie entworfen" ("Atlas of Geomagnetism: According to the Elements of the Theory of Design"), a series of magnetic maps. In 1845, Goldschmidt published, also in German, a book on electromagnetism, "Untersuchungen über die magnetische Declination in Göttingen" ("Studies of the Magnetic Declination in Göttingen").
