He used a liquid battery to send an electric current through a small coil. When it was moved in or out of a larger coil, its magnetic field induced a momentary voltage in the small coil that was detected by a galvanometer. Scottish mathematical physicist James Clerk Maxwell (1831 1879) expressed the time varying aspect of electromagnetic induction as a differential equation that became known as Faraday s Law. Although Faraday was first to publish his work, American scientist Joseph Henry (1797 1878) independently made the same discovery in 1832."--Computer History Museum.

"Henry independently discovered electro-magnetic induction and in this paper announced his discovery of electric self-induction, one of the prime properies of an electro-magnetic circuit. Henry was an eminent experimenter but was casual in publishing his findings with resulting lack of recognition of his contributions."(Bern Dibner).Dibner "Heralds of Sciece", No.63.It was also printed the same year in "Transactions of the American Philosophical Society, New Series, Vol. 5". The paper was later printed in "Philosophical Magazine", 1840."The direction of Henry?s thought became somewhat apparent in his 1835 paper (refers to the papers reading before the American Phil. Soc., febr. 6th, 1835) on the action of a spiral conductor in increasing the intensity of galvanic currents. The paper started out as an affirmation of Henry?s priority in the discovery of self-induction. He then combined induction proper (using Faraday?s findings and his own) with selfinduction to show how these produce a pattern of repulsions yielding an increased effect in spirals. He specifically linked these ?magneto-electrical? results to the principles of static induction developed by Cavendish and Poisson. This explanation was then applied to Savary?s report of changes of polarity when magnetic needles were placed at varying distances from a wire in which a current was being transmitted ("Mémoire sur l?aimantation," in Annales de chimie et de physique, 34 [1827], That is, currents appeared periodically in the air surrounding a current-bearing straight wire as a result of the actions of induction and self-induction."

(The entire issue offered). Henry's paper: pp. 282-312. First German version of Henry's description of his discovery of self-induction. He missed the credit for the discovery of induction to Faraday, but he had done the key experiment ahead of Faraday, but Faraday was the first to publish. But he is credited for the discovery of self-induction (1832) and Faraday discovered it independently two years later (1834)."In Henry's paper, however, he explained thet the electric current in a coil can induce another current not only in another coil but in itself. The actual current observed in the coil is, then, the combination of the original current and the induced current. This is called self induction."(Isac Asimov).The issue contains further notable papers Michael Faraday's "Vierzehnte Reihe von Experimental-Untersuchungen über Elektricität", § 2o-22. (Nos 1667-1748). Pp. 249-281. First German version. In this paper FARADAYamplifies his theory of electrostatic induction by making further use of the analogy with the induction of magnetism.

Stamp to verso of titlepage and verso of plates. Clean and fine, printed on good paper. First appearance in German - prepared by Faraday himself for publication in Annalen - of two groundbreakings papers in chemistry and physiscs.In the FIRST PAPER (8. Reihe) Faraday brings forth the idea "that the atoms of matter are in some way endowed or associated with electrical powers, to which they owe their most striking qualities, and amongst them their mutual chemical affinity." He showed how natural it is to suppose that the electricity which passes through the electrolyte is exact equivaklent of that which is possessed by the atoms separated at the electrode: which implies that there is A CERTAIN ABSOLUTE QUANTITY OF THE ELECTRIC POWER ASSOCIATED WITH EACH ATOM OF MATTER.- Faraday further verifies, that the electricity of the violtaic pile is proportionate in its intensity to the intensity of the affinities concerned in its production. - Dealing with the the decompositions in electrolysis, he shows that THE FORCES TERMED CHEMICAL AFFINITY AND ELECTRICITY ARE THE SAME.In the SECOND PAPER (9. Reihe), Faraday (independent of Henry's discovery of the same phenomena in 1832) discovers SELF-INDUCTION or the "extra current" and points out the importent influence it must have in the construction of electro-magnetic machines (electro-motors)."Faraday showed that the powerful momentary current, which was observed when the circuit was interrupted, was really an induced current governed by the same laws as all other induced currents, but with this peculiarity, that the induced and inducing current now flowed in the same circuit. In fact, the current in its steady state establishes in the surrounding region a magnetic field, whose lines of force are linked with the circuit" and teh removal of these lines of forcewhen the circuit is broken originates an induced current, which reatly reinforces the primary current just before its final extinction."(Whittaker in "A History of the Aether and Electricity")"In the series of experiments which are detailed in this paper, the author inquires into the causes of some remarkable phenomena relating to the action of an electrical current upon itself, under certain circumstances, wherby its intensity is highly exalted, and occasionally increased to ten, twenty, or even fifty times that which it originally possessed."(Abstract).

A stamp to verso of frontispiece (Library of Congress duplicate stamp). First printing of this importent paper, the first to describe in detail how the phenomena of Self-Induction was discovered. Henry discovered the induction phenomena - how an electric current in one coil may set up a current in the other through the development of the magnetic field - independently of Faraday, but Faraday was first to publish on electromagnetic induction. Henry's experiments with induction led him to his importent discovery of SELF-INDUCTION, which is the phenomenon in which a change in electric current in a coil produces an induced emf in the coil itself. This phenomenon was also discovered inependently by Faraday, but this time Henry had published first. The basic unit of inductance was to be called "the Henry". Relevant to the controversy between Faraday and Henry is the following statement by A D Bache, Secretary of the American Philosophical Society introducing an abstract of Henry in J Franklyn Inst. 1835 pp. 169-70 (H. Norman 1053 and the paper offerd): "A memoir on this subject has been since submitted to the Society, containing an extension of the subject, the primary fact in relation to which was observed by Professor Henry as early as 1832, and announced by him in the American Journal of Science. Mr. Faraday having recently entered upon a similar train of observations, the immediate publication of the accompanying is important, that the prior claims of our fellow countryman may not be overlooked."(Spark Museum).Magee "Source Book in Physics", p. 515.

Note), pp. 83-123 a. 1 engravd plate and pp. 125-168 First appearance of 3 fundamental papers in electromagnetic theory in which Faraday presents his discoveries of the so-called "specific inductive capacity" of the insulator, - showing that the behaviour of a diaelectric is exactly the same as that of an electrolyte up to a certain point, - that induction appears to be the first step, and decomposition the second, - that 'Insulators' "may be said to bodies whose particles can retain the polarised state, whilst conductors are those whose particles cannot be permanently polarised", - that the lines of force dispose themselves as if they were subject to a mutual repulsion, or as if the tubes of force had an inherent tendency to dilate.From 1831 to 1852 Michael Faraday published his "Experimental Researches in Electricity" in The Philosophical Transactions of the Royal Society. These papers contain not only an impressive series of experimental discoveries, but also a collection of heterodox theoretical concepts on the nature of these phenomena expressed in terms of lines of forces and fields. He published 30 papers in all under this general title.They represents Faraday's most importent work, are classics in both chemistry and physics and are the experimental foundations for Maxwell's electro-magnetic theory of light, using Faraday's concepts of lines of force or tubes of magnetic and electrical forces. His many experiments on the effects of electricity and magnetism presented in these papers lead to the fundamental discoveries of 'induced electricity' (the Farday current), the electronic state of matter, the identity of electricity from different sources, equivalents in electro-chemical decomposition, electrostatic induction, hydro-electricity, diamagnetism, relation of gravity to electricity, atmospheric magnetism and many other."Among experimental philosophers Faraday holds by universal consent the foremost place. The memoirs in which his discoveries are enshrined will never cease to be read with admiration and delight" and future generations will preserve with an affection not less enduring the personal records and familiar letters, which recall the memory of his humble and unselfish spirit."(Edmund Whittaker in A History of the Theories of Aether and Electricity).
