‎First edition of Oersted's main work on natural philosophy. Oersted is universally known for his discovery of Electro-Magnetism in 1820. Afterwards he went on to write a number of important philosophical works on natural philosophy and empiricism, of which he considered ""Aanden i Naturen"" as his main work. The work is found printed on 2 sorts of paper, common- and vellum paper, the present copy being on vellum. Both Hans Christian Andersen and Søren Kierkegaard admit to having been influenced by the writings of Oersted. ""He was an enthusiastic follower of the ""Naturphilosophie"" school in Germany, whose main object was the unification of physical forces, thus producing a monistic theory of the universe.

‎The exceedingly rare very first announcement of H. C. Ørsted’s landmark discovery of electromagnetism, predating his famous “Experimenta”-paper by at least a week. Publishing the present brief note allowed him to quickly claim priority for his discovery, which ensured that his work would be recognized and attributed to him before others potentially stole his discovery. The importance of the discovery of electromagnetism, one of the most pivotal moments in the history of science, can hardly be overestimated. Here, Ørsted laid both the theoretical and practical foundation for future works of Faraday, Maxwell, and Hertz. The offered paper was published in the 28th week of July, 1820 (No. 28 of the periodical), which means that it was published some time between July 11 and July 16, probably the 11th or 12th. The paper which made Oersted famous all over Europe was his Latin pamphlet ""Experimenta circa effectum conflictus electrici in acun magneticam. Hafniæ, 1820"", dated July 21, 1820. The Latin “Experimenta” was sent on the same day (according to Kirstine Meyer in ""Scientific Life and Works of H.C. Ørsted"") to learned bodies and scholars in all European countries. The communication offered here (in Danish) was published at least a week before ""Experimenta"". The essence of Oersted's discovery is detailed in the paper offered here, where he describes how the magnetic effect of an electric current-carrying wire was initially observed using an incandescent platinum wire. He then extended his experiments to non-incandescent wires made from various materials noting that the magnetic effect was influenced by the wire's dimensions. Among Oersted's papers (now in the holding of the Danish Royal Library), we have both a draft written in his own hand on acid-stained paper and a nearly identical version in another handwriting. These experimental notes form the basis of the present paper (which Kirstine Meyer refers to as ""Supplement II""). In Supplements III and IV (dated July 15 and 21), Oersted further elaborates on his experiments with the wire in different positions relative to the magnet which became his “Experimenta”-paper. “Electromagnetism itself was discovered in the year 1820, by Professor Hans Christian Oersted, of the University of Copenhagen. Throughout his literary career, he adhered to the opinion, that the magnetical effects are produced by the same powers as the electrical. He was not so much led to this, by the reasons commonly alleged for this opinion, as by the philosophical principle, that all phenomena are produced by the same original power. … His researches upon this subject, were still fruitless, until the year 1820. In the winter of 1819–20, he delivered a course of lectures upon electricity, galvanism, and magnetism, before an audience that had been previously acquainted with the principles of natural philosophy. In composing the lecture, in which he was to treat of the analogy between electricity and magnetism, he conjectured, that if it were possible to produce any magnetical effect by electricity, this could not be in the direction of the current, since this had been so often tried in vain, but that it must be produced by a lateral action. This was strictly connected with his other ideas" for he did not consider the transmission of electricity through a conductor as an uniform stream, but as a succession of interruptions and reestablishments of equilibrium, in such a manner that the electrical powers in the current were not in quiet equilibrium, but in a state of continual conflict.… The plan of the first experiment was to make the current of a little galvanic trough apparatus, commonly used in his lectures, pass through a very thin platina wire, which was placed over a compass covered with glass. The preparations for the experiments were made, but some accident having hindered him from trying it before the lecture, he intended to defer it to another opportunity yet during the lecture, the probability of its success appeared stronger, so that he made the first experiment in the presence of the audience. The magnetical needle, though included in a box, was disturbed but as the effect was very feeble, and must, before its law was discovered, seem very irregular, the experiment made no strong impression on the audience [“Thermo-electricity,” in Edinburgh Encyclopaedia (1830), XVIII, 573–589" repr. in Oersted’s Scientific Papers, II, 356]. “We have now reached the spring of 1820. Ørsted understood that the “feeble” disturbance of the compass needle seen in his lecture demonstration was a genuinely important discovery. Other duties prevented a more detailed and quantitative investigation of this effect until the beginning of July 1820. Ørsted had new laboratory facilities and a more powerful galvanic apparatus that facilitated his measurements. Confident that his experiments would have a successful outcome, he gathered a group of six distinguished observers who would serve as witnesses of his experiments. (Their names and credentials were duly noted in the written description of his investigations.) He set about an exhaustive series of measurements aimed at documenting how the distance and orientation of a current-carrying wire affected the deflection of a compass needle. He made copious notes and drawings, many of which can be seen in Det Kongelige Bibliotek in Copenhagen. ” (Karen Jelved & Andrew D. Jackson, H. C. Ørsted and the Discovery of Electromagnetism, 2019). But before the above mentioned Latin paper was published - which within the same year was reprinted in England, France, Germany and Italy - Oersted made sure to secure his discovery and consequently eternal fame by publishing the present paper.OCLC only list three copies (Danish Royal Library, Houghton, Harvard, USA & British Library).

‎Originaltrykket af Ørsteds første bog, som er meget sjældent forkommende. Scarce first edition of Hans Christian Oersted's first printed book (The Science of the General Laws of Nature). Oersted is universally known for his discovery of the Electro-Magnetism in 1820. In this his first printed book, Oersted proposes at least three theses that he were to follow for the rest of his life, and which he made the foundation for his discovery of Electro-Magnetism: the crucial role that experiments and thereby empiricism play in the perception of nature the fact that each individual phenomenon in nature in accordance with the philosophy of nature must be understood as a whole" and that the laws of nature are the same everywhere, in the smallest and in the greatest parts of the universe. The sort of philosophy of nature that Oersted studies and develops is by him comprehended as a product of human striving towards with its reason to ""include and penetrate the entire nature, and to explain it in its full context"" (from ""Science of the General Laws of Nature"" - own translation), which is why this philosophy is also the science of the general laws of nature (that are the same everywhere). It thus not only includes the science of movement, but also that of electricity, magnetism, light, warmth, and chemical connections, such as they all follow directly from ordinary forces of nature, and Oested's discovery in 1820 of the connection between magnetism and electricity must be seen in this connection.Both H.C. Andersen and Søren Kierkegaard admit to having been influenced by the writings of Oersted. ""He was an enthusiastic follower of the ""Naturphilosophie"" school in Germany, whose main object was the unification of physical forces, thus producing a monistic theory of the universe. It was to further this purpose that Oersted sought in actual phenomena the electro-magnetic identity of which he had already convinced himself on metaphysical grounds"" (Percy H.

‎First edition of the first German translation (by Gilbert) of Oersted's epoch-making announcement of his discovery of electromagnetism, printed in the same year as the Latin original. The work originally appeared in Latin as ""Experimenta circa effectum conflictus electrici in acun magneticam. Hafniæ, 1820"""" this Latin pamphlet is impossibly scarce and only a few copies are known, as it was privately printed in a very small number and was only distributed to colleagues in Europe. This discovery and confirmation of the connection between 2 forces, electricity and magnetism, must be considered one of the happiest events in the history of science, both with regard to scientific and practical results.""From the moment that Ørsted's discovery became known it created an enormous sensation. The results communicated were so astounding that they were received with a certain distrust, but they were stated with such accuracy that it could hardly be permitted to entertain any doubts. In the course of a short time the treatise was translated into all the chief languages."" (Kirstine Meyer). In a note Gilbert says, that it is a word by word translation of Oersted's small Latin pamphlet, ""Eine fast wörtliche Uebersetzung des einzeln gedruckten, lateinischen, de 21 Juli 1820 geschriebenen Viertel-Bogens, de von Hrn. Oersted mehreren zugeschicht worden ist...""When Oersted's discovery became known to European physicists they became busy with testing Oersted's results"" thus, this volume of ""Annalen"" contains some important papers on electromagnetism in German: Gilbert: Untersuchungen über die Einwirkung des geschlossenen galvanisch-electrischen Kreises uaf die Magnetnadel. pp. 331-391" Biot & Savart: Von einer Abhandlung über die Magnetismus der Voltaischen Sáule (The Law of Biot & Savart), pp. 392-394 (German extract) Yelin: Ueber den Zusammenhang der Electricität mit dem Magnetismus...mit einigen Zusätzen von Gilbert.
