Ernst Gumlich

Ernst Carl Adolph Gumlich (born April 23, 1859 in Maple , † February 12, 1930 in Berlin ) was a German physicist .

His father Johann Karl Ernst Gumlich (* 1816) was pastor in Heldritt and Ahorn and from 1868 Oberpfarrer of Neustadt.

From Easter 1878 he studied physics , mathematics and natural sciences in Jena , Tübingen and Berlin. In 1883 he passed the senior teacher exam in Berlin and in 1885 he received his doctorate in Jena for the "Theory of Newtonian color rings in the continuous light". From 1887 he was an employee at the Physikalisch Technische Reichsanstalt in Berlin. In 1898 he became professor and director of the local magnetic laboratory. He was appointed a secret government councilor.

Gumlich mainly investigated magnetic materials in the case of alternating magnetization, such as the course of the eddy current and hysteresis losses . He also developed measurement methods for magnetic properties such as the yoke-isthmus method and improved the Epstein method .

He recognized the parallelism of the ferromagnetic properties, especially with the electrical conductivity . In the summer of 1900, he discovered that even a small addition of silicon in the iron multiplied the electrical resistivity and thus the eddy current losses could be significantly reduced , with the same magnetic properties . [1] He suggested the rolling mills for producing alloy sheets ( dynamo sheet on). [2]

Gumlich's grave is located on the southwestern cemetery Stahnsdorf .

Buried:
Standsdorf Cemetery
