The Story of Great Inventions 2011-10-05T02:00:16.353Z Oersted’s comment that the voltaic apparatus used should “be strong enough to heat a metallic wire red hot” does not excuse the 20-year delay of the discovery. The Earliest Electromagnetic Instruments This was, of course, long prior to the discovery, by Oersted, in 1820, of the real connexion between magnetism and the electric current. On the magnet, magnetick bodies also, and on the great magnet the earth a new physiology, demonstrated by many arguments & experiments Oersted’s discovery in 1819 was indeed epoch-making in the degree to which it stimulated other research.

The Scrap Book, Volume 1, No. 6 August 1906 The sketch is the editor’s interpretation of a verbal description given him by a visiting Danish chemist who, in turn, had received the information in a letter from Oersted. The Earliest Electromagnetic Instruments Oersted, of Copenhagen, made important discoveries in electromagnetism. The Scrap Book. Volume 1, No. 2 April 1906 To take a simple instance, if we consider an electric current as flowing in a conductor it is, as Oersted discovered, surrounded by closed lines of magnetic force. Encyclopaedia Britannica, 11th Edition, Volume 9, Slice 2 "Ehud" to "Electroscope" 2011-01-29T03:00:23.777Z To Professor Oersted is also due the important discovery, that electro-magnetic effects do not depend upon the intensity of the electricity, but solely on its quantity. The International Monthly, Volume 3, No. 2, May, 1851 Starting from the discovery of Oersted, the celebrated French philosopher had shown that all the phenomena of magnetism then known might be reduced to the mutual attractions and repulsions of electric currents. Little Masterpieces of Science: Invention and Discovery This view underlies the many attempts to correlate the Oersted phenomena with cell materials and design, and with the use of such terms as “chemical magnetism” by Erman and others. The Earliest Electromagnetic Instruments One day devoted to seeing Germany, and one for the North, the country of Oersted and Linnaeus, and for Norway, the land of the old heroes and the young Normans. Fairy Tales of Hans Christian Andersen One day devoted to seeing Germany, and one for the North, the country of Oersted and Linnæus, and for Norway, the land of the old heroes and the young Normans. What the Moon Saw: and Other Tales Christian Oersted was sent to Copenhagen to study medicine. The International Monthly, Volume 3, No. 2, May, 1851 Oersted first proved that the other part of its life is spent on the leaves of certain Rosaceæ, and his discovery has been repeatedly confirmed. Scientific American Supplement, No. 664, September 22,1888 Despite the many uses made of voltaic cells after Volta’s announcement of his “pile” invention in 1800, two decades passed before Oersted discovered the magnetic effects of a voltaic circuit. The Earliest Electromagnetic Instruments Denmark and the whole world knows them—the two brothers Oersted. Fairy Tales of Hans Christian Andersen The facts of nature are perceived by our senses; the thoughts of nature, to borrow an expression of Oersted's, can be conceived by our reason only. The Continental Monthly, Vol. 6, No 4, August, 1864 Devoted To Literature And National Policy No experiment appears, however, to have been made to determine the question until 1820, when Oersted placed a magnetic needle within the influence of a wire connecting the extremities with a voltaic battery. The International Monthly, Volume 3, No. 2, May, 1851 Professor Oersted suggests the name “storm-pillar,” as being a more appropriate term. The Ocean and its Wonders Oersted himself held this latter opinion, and had been seeking electromagnetic relationships more or less deliberately for several years before he made his decisive observations. The Earliest Electromagnetic Instruments As Franklin had exhibited the relation between lightning and the electric fluid, so Oersted exhibited the relation between magnetism and electricity. Something of Men I Have Known With Some Papers of a General Nature, Political, Historical, and Retrospective The most striking presentation ever made of the argument, perhaps, is that in Oersted's essay on the "Universe as a Single Intellectual Realm." The Destiny of the Soul A Critical History of the Doctrine of a Future Life The character of Professor Oersted's mind was essentially searching and minute; thus he observed results which escaped detection in the hands of those who took more general and enlarged views of natural phenomena. The International Monthly, Volume 3, No. 2, May, 1851 During that year Oersted discovered that an electric current would deflect a magnetic needle, thus showing that there was some relationship between electric and magnetic force. Scientific American Supplement, No. 717, September 28, 1889 He began by referring to Oersted’s discovery as “the most interesting to be presented in a thousand years of the history of magnetism.” The Earliest Electromagnetic Instruments W. of Cepheus, close to the brilliant crater, there is a cleft or narrow valley running N. towards Oersted. The Moon A Full Description and Map of its Principal Physical Features The brilliant discoveries of Oersted, Arago, and Faraday have established a more intimate connection between the electric tension of the atmosphere and the magnetic tension of our terrestrial globe. COSMOS: A Sketch of the Physical Description of the Universe, Vol. 1 This was the work of Hans Christian Oersted, a native of Denmark. Masters of Space Morse, Thompson, Bell, Marconi, Carty Akin to these are those titles which have been imitated, in other words, half stolen; for instance, a long time after I had written "On Will in Nature," Oersted wrote "On Mind in Nature." Essays of Schopenhauer A single turn suffices, however, to demonstrate Oersted’s experiments, using small strips of zinc and copper dipped in ammonium-chloride solution. The Earliest Electromagnetic Instruments The electric currents of Berzelius and Oersted, the crucible of Wohler, the closed furnaces and the hydrogen gas of the French manufacturers and the Bessemer converter apparatus of Thompson, all indicate one direction. Scientific American Supplement, No. 531, March 6, 1886 We went to the Porcelain Manufactory, and, singularly enough, met there the daughter of Oersted, to whom I had the pleasure of an introduction. Samuel F. B. Morse, His Letters and Journals In Two Volumes, Volume II A development of Oersted's demonstration with the compass needle was used to construct the world's first system of signaling by the use of electricity. The Dawn of Amateur Radio in the U.K. and Greece: a personal view Oersted demonstrated from inductive reasoning that every conductor of electricity possessed all the known properties of a magnet while a current of electricity was passing through it. Scientific American Supplement, No. 417, December 29, 1883 Oersted succeeded in electromagnetic research by using a spark-producing cell, which could make a wire glow. The Earliest Electromagnetic Instruments Of the two brothers Oersted, one, a lawyer and statesman, has done much to establish the principles of state economy, while the discoveries of the other entitle him to the highest rank in physical science. Handbook of Universal Literature From the Best and Latest Authorities Oersted was a most amiable man and universally beloved. Samuel F. B. Morse, His Letters and Journals In Two Volumes, Volume II With this exception what impressed me most of all that I heard in the lessons was Anders Sandöe Oersted's Interpretation of the Law. Recollections of My Childhood and Youth Both Galvani and Volta passed into shadow, when, in 1820, Professor H. C. Oersted, of Copenhagen, discovered the law upon which were afterwards slowly built the electrical appliances of modern life. Steam, Steel and Electricity A similar amount is concerned with refuting various proposals, such as those of Berzelius and Erman, about distributions of magnetic polarity in a conducting wire to account for Oersted’s results. The Earliest Electromagnetic Instruments Collin and Oersted secretly associated themselves with him, and became my intercessors. True Story of My Life Oersted showed that an electric current is invariably attended by magnetic effects; Faraday showed that magnetic changes are invariably attended by electric currents. Beacon Lights of History, Volume 14 The New Era; A Supplementary Volume, by Recent Writers, as Set Forth in the Preface and Table of Contents But this Oersted very often did prove in an irrefutable manner. Recollections of My Childhood and Youth A magnet must be made man, in some Gilbert, or Swedenborg, or Oersted, before the general mind can come to entertain its powers. Representative Men The paper is primarily a review of Oersted’s work, with references to electromagnetic observations before Oersted, and accounts of various related but nonmultiplier experiments that Cumming has made. The Earliest Electromagnetic Instruments Collin was my counsellor in practical life, and Oersted in my literary affairs. True Story of My Life Faraday was convinced that if electrical processes are accompanied by magnetic forces, as Oersted had shown, the reverse must also be true - magnetism must be accompanied by electricity. Man or Matter Oersted was on the outlook for the required clue, and a happy chance is said to have rewarded him. The Story of Electricity Following them came a group of master builders, among whom may be mentioned: Volta of Italy, Oersted of Denmark, Ampere of France, Ohm of Germany, Faraday of England, and Joseph Henry of America. The Age of Invention : a chronicle of mechanical conquest The effect of Oersted's demonstration is almost incomprehensible. A History of Science — Volume 3 In Berlin, a letter of Oersted's procured me the acquaintance of Chamisso. True Story of My Life Starting from the discovery of Oersted, the illustrious French philosopher had shown that all the phenomena of magnetism then known might be reduced to the mutual attractions and repulsions of electric currents. Faraday as a Discoverer Ampere of Paris, following Oersted, promptly showed that two parallel wires carrying currents attracted each other when the currents flowed in the same direction, and repelled each other when they flowed in opposite directions. The Story of Electricity Admiring, as we most sincerely do, the electro-magnetic discoveries of Professor Oersted and his followers, we still, as chemists, fear that our science has suffered some degree of neglect in consequence of them. Reflections on the Decline of Science in England The first experiments in connection with the subject which I am undertaking to explain," wrote Oersted, "were made during the course of lectures which I held last winter on electricity and magnetism. A History of Science — Volume 3 I had brought with me a letter of introduction from Oersted, to the celebrated Berzelius, who gave me a good reception in the old city of Upsala. True Story of My Life The beautiful experiments of Seebeck and Peltier show the convertibility of heat and electricity; and others by Oersted and myself show the convertibility of electricity and magnetism. Faraday as a Discoverer We come now to another consequence of Oersted's great discovery, which is doubtless the most important of all, namely, the generation of electricity from magnetism, or, as it is usually called, magneto-electric induction. The Story of Electricity This was followed by a paper on magnetism, by Professor Oersted; and several other memoirs were then read. Reflections on the Decline of Science in England But in that year it occurred to Jean Christian Oersted, of Denmark, to pass a current of electricity through a wire held parallel with, but not quite touching, a suspended magnetic needle. A History of Science — Volume 3 It became practicable, however, when Oersted discovered that a magnetic needle could be swung to one side or the other by an electric current passing near it.
