  2. History of geomagnetism - Wikipedia

    en.wikipedia.org/wiki/History_of_geomagnetism

    A reconstruction of an early Chinese compass. A spoon made of lodestone, its handle pointing south, was mounted on a brass plate with astrological symbols. [1]The history of geomagnetism is concerned with the history of the study of Earth's magnetic field.

  3. John Henry Lefroy - Wikipedia

    Sir John Henry Lefroy 1817–1890: A pioneer in the study of terrestrial magnetism, Lefroy was director of the magnetic observatory here from 1842 to 1853. Born in Hampshire, England, he was commissioned in the Royal Artillery at the age of seventeen and, because of his aptitude for science, was posted to St. Helena in 1839 to establish a ...

    He made particularly important studies of terrestrial magnetism, discovering (1841) that it is practically unaffected by the moon and writing Anleitung zu den magnetischen Beobachtungen (second edition, 1858). Many automatically registering meteorological machines were devised by him.

    January 27 – John James Audubon (born 1785), naturalist and illustrator. February 18 – Carl Gustav Jakob Jacobi (born 1804), mathematician. March 9 – Hans Christian Ørsted (born 1777), physicist.

  7. Magnetostratigraphy - Wikipedia

    en.wikipedia.org/wiki/Magnetostratigraphy

    The magnetic property most useful in stratigraphic work is the change in the direction of the remanent magnetization of the rocks, caused by reversals in the polarity of the Earth's magnetic field. The direction of the remnant magnetic polarity recorded in the stratigraphic sequence can be used as the basis for the subdivision of the sequence ...

    Adolf Friedrich Karl Schmidt (July 23, 1860 – October 17, 1944) was a German geophysicist who examined geomagnetism. He was involved in both experimental studies and in theoretical work on geomagnetism.

    The journal was originally founded under the name Terrestrial Magnetism by the American Geophysical Union's president Louis Agricola Bauer in 1896. [2] [3] It was renamed to Terrestrial Magnetism and Atmospheric Electricity in 1899 and in 1948 it acquired its current name. [4]
