Experimental Researches in Electricity
Michael Faraday
1839 |
This is a
superb collection of first editions of many of Faraday's most important
papers, including his greatest paper, Series I of Experimental
Researches in Electricity, in which he demonstrates the means for
generating electricity by electromagnetic induction. Each paper, article or
review extracted from the journal in which it originally appeared; the
collection was purchased from the distinguished science library of Haskell
F. Norman.
Michael
Faraday (1791 - 1867) was "one of the greatest physicists of the 19th
century and one of the finest experimenters of all time. His principal
contributions were made in advancing our knowledge of the nature and
potentialities of electricity... he enunciated his theory of `lines' or
`tubes' of magnetic force which was the starting point for, the
revolutionary theories of Clerk Maxwell and later of Einstein... [his
discoveries] laid the foundation of the modern electrical industry‑electric
light and power, telephony, wireless telegraphy, television, etc."1
The present collection encompasses the entire range of Faraday's remarkable
achievement, including his breakthrough discovery of electromagnetic
induction (Phil. Trans., Series 1‑2), his first general theory of
electricity as a function of interparticulate strain (Phil. Trans., Series
11‑13), and his last major series of researches on magnetism (Phil. Trans.,
Series 19‑21) "containing the germ of modern field theory," from which Clerk
Maxwell and .Einstein developed their own theories6.

Including Faraday's greatest paper, reporting his
discovery of the means for generating electricity by electro-magnetic
induction. "Faraday became convinced that the relation of electricity to
magnetism had to be extended, and that if a current could produce a magnetic
field, a magnetic field also had to be able to produce a current. . . .
Faraday brooded over [this problem] for about ten years, and made numerous
experiments, all negative. . . . In the summer [of 1831], he built an iron
ring on which he wrapped two coils of copper wire. He then noted that if he
sent a current in one and connected the other to a galvanometer, the
instrument would signal a current not in the stationary state, but only at
the establishment or interruption of a current in the other coil. That was
the clue he needed. By the end of September he had developed a clear
understanding and experimental demonstration of electromagnetic induction.
He had grasped the vital point that to generate a current, a conductor had
to cut the lines of magnetic force. . . . Once the nature of electromagnetic
induction was understood, Faraday was able to explain Arago's observations
and to invent an electromagnetic generator of currents—a primitive dynamo" (Segrè,
Falling Bodies to Radio Waves, pp. 143-44; also 132-55). Dibner 64. Horblit

The other extracts gathered here, 102 from Quarterly
Journal of Science, 1816‑30, and 13 extracts from Annals of Philosophy,
1821‑26, include Faraday's first published paper, "Analysis of the native
caustic Lime" (QJS, 1816); his 1825 paper announcing the discovery of
benzene; his early "Historical Sketch of Electro‑magnetism" (1821),
requested by editor Richard Phillips and contributed anonymously; his
groundbreaking 1821 paper "On some new Electro‑Magnetical Motions, and the
Theory of Magnetism," which records the first conversion of electrical into
mechanical energy‑this paper also contains the first notion of the line of
force (DSB)‑and three important follow‑up papers from the same year. The 30
Series of Experimental Researches in Electricity were collected in book form
in three volumes dated 1839, 1844 and 1859, after the papers appeared in
Philosophical Transactions. Series 3‑10, not collected here, deal primarily
with electrochemistry, in which Faraday demonstrates the common identity of
all forms of electricity; Series 23‑30, also not collected here, elaborate
further on his earlier revolutionary discoveries.10 The other
