  Christopher Hansteen - LoveToKnow 1911
CHRISTOPHER HANSTEEN (1784-1873), Norwegian astronomer and physicist, was born at Christiania, on the 26th of September 1784.
By the rules there framed for the observation of magnetical phenomena Hansteen hoped to accumulate analyses for determining the number and position of the magnetic poles of the earth.
Shortly after the return of the mission, an observatory was erected in the park of Christiania (1833), and Hansteen was appointed director.

 Christopher Hansteen - Wikipedia, the free encyclopedia
Christopher Hansteen (September 26, 1784–April 11, 1873) was a Norwegian astronomer and physicist.
The Hansteen crater on the Moon is named for him.
Aasta Hansteen, a noted Norwegian feminist and painter, was Christopher Hansteen's daughter.

 NAHA // Norwegian-American Studies
The daughter of Christopher Hansteen, a distinguished early professor at the University of Oslo, Aasta Hansteen (1824-1908) was well known in the intellectual and upper-class circles in Norway’s capital, for her unconventional behavior set her apart from her contemporaries.
Of major importance to Aasta Hansteen’s perception of the changing political climate in her homeland was the appearance in 1887 of a Norwegian periodical for women.
The warm and genuine enthusiasm which Aasta Hansteen displayed for the American women’s movement and her clear endorsement of its models were integral elements of her American experience and a necessary prerequisite for her characterization of America as “det første sted paa jorden for kvinder” (the best place on earth for women).

 Hansteen Christopher (1784-1873)
Hansteen, a physicist and astronomer from Norway, devoted his time to the study of geomagnetism.
In 1701 Halley had already published a map of magnetic declinations, and the subject was studied by Humboldt, de Borda, and Gay-Lussac, among others.
Hansteen collected available data and also mounted an expedition to Siberia, where he took many measurements for an atlas of magnetic strength and declination

 HANSTEEN, Christopher, THEORY OF TERRESTRIAL MAGNETISM -- Untersuchungen uber den magnetismus der erde....   (Site not responding. Last check: 2007-11-06)
Hansteen was the foremost proponent of the nineteenth-century theory that Earth has two magnetic axes (or four poles).
Hansteen could not accept a single-axis, two pole theory partly because the magnetic equator (the path along which the magnetic inclination or dip is zero) is not a great circle.
Humboldt and Gauss were among the many that Hansteen inspired, laying the foundation of our knowledge and awareness of the laws of terrestrial magnetism.The text and the atlas were published separately and are rarely found together.

 Geomagnetic Theories from 1800 to 1900
Hansteen carefully distinguished between "points of force" and "points of convergence", the former being to him the real magnetic poles and the latter a superficial appearance (Good, Follow the Needle, p.
The main distinction between Halley's and Hansteen's theories was that whereas Halley lacked a law of magnetic attraction, Hansteen used quantitative laws and could calculate from his theory the declination and other magnetic variables that should be observed at various locations on Earth (Hansteen, chs.
Hansteen did not entirely forswear speculation about the ultimate cause of magnetism, but he carried his application of quantitative law to geomagnetism much further than his predecessors had.

 Geomagnetism - Early Concept of the North Magnetic Pole
Hansteen believed that the observed pattern of the magnetic field could be explained by two magnetic axes, each with two poles, but his definition of what constituted a magnetic pole differs from the definition we use today.
According to Hansteen, a magnetic pole is not a point where the magnetic field is vertical, nor is it a point towards which a compass needle points.
Some interpreted it to mean the point at which magnetic meridians converged; others, including Hansteen took it to mean the area at which magnetic intensity was a maximum; and a third group, which included James Ross, defined it to mean the point of vertical dip.

 Christopher Hansteen
In 1819 he published a volume of researches on terrestrial magnetism, which was translated into German by P. Hanson, under the title of Untersuchungen über den Magnetismus der Erde, with a supplement containing Beobachtungen der Abweichung und Neigung der Magnetnadel and an atlas.
In prosecution of his researches he travelled over Finland and the greater part of his own country; and in 1828-30 he undertook, in company with G. Erman, and with the cooperation of Russia, a government mission to Western Siberia.
Shortly nfter the return of the mission, an observatory was erected in the park of Christiania (1833), and Hansteen was appointed director.

 Theosophy and magnetism
However, as Edge indicates, the person KH is referring to is certainly Christopher Hansteen – and not the astronomer John Flamsteed (1646-1719).
Neither Halley nor Hansteen spoke of magnetic poles above the earth's surface, but both proposed that there were two magnetic poles in each hemisphere, though their theories were otherwise very different.
Hansteen's definition of what constituted a magnetic pole differs from the definition we use today.

 The road to the magnetic north pole   (Site not responding. Last check: 2007-11-06)
It is a common belief that Christopher Columbus discovered magnetic deviation during his first trip to America in 1492, but the phenomenon was in fact known in central Europe earlier among mariners.
Hansteen became well known in international as well as Norwegian research circles and made many contributions to the Norwegian community right up to his death in 1873.
Hansteen’s description, however, did not survive long: the great German mathematician, Carl Friedrich Gauss (1777-1855), attacked the problem with characteristic elegance, and, in 1838, presented a mathematical description which is still in use today.

On reaching Copenhagen, Abel found that Degen had died and he changed his mind about taking Hansteen's advice to go directly to Paris, preferring not to travel alone and stay with his friends who were going to Berlin.
Hansteen received a major grant to investigate the Earth's magnetic field in Siberia and a replacement was needed to teach for him at the University and also at the Military Academy.

Hansteen thought this to be impossible, and wanted to see it right away.
It was, however, the most fantastic waterfall professor Hansteen had ever seen, and he measured its height to 933 feet (280 meters) by throwing stones over the egde and measuring the time before they reached the bottom, using his pocket watch.
After his return to Oslo, Hansteen wrote a masterpiece of an article in the magazine "Budstikken", and very soon Vöringsfossen became a destination that most tourists in the area "had" to visit.

      Sabine long believed in Christopher Hansteen’s theory that the earth had two magnetic poles in each hemisphere and that there was a correlation between magnetic and meteorological phenomena.
His reputation scarcely suffered even from his advocacy of Hansteen’s erroneous views about terrestrial magnetism or from his refusal to adopt the theory that limited the origins of magnetism to the interior of the earth.
Sabine continued to see magnetism as essentially a part of meteorology, and his research programmes were based on the view that different geophysical phenomena were interrelated.

Abel was particularly intrigued by Gauss's remark in Section VII of that work, where Gauss states that his theory of the divisions of the circular functions could be applied to the lemniscate and elliptical functions as well.
Hansteen was a direct collaborator with Gauss, Alexander von Humboldt, and Dallas Bache, in the Magnetic Union and he was responsible for taking magnetic measurements throughout northern Europe.
Recognizing Abel's potential, Holmboe and Hansteen arranged to finance a tour of the continent so that Abel could interact with the leading thinkers of his day.
