Professor Faraday's lecture, with which, according to use and custom, the Friday evening course at the Royal Institution was opened, has been the most noteworthy topic of scientific gossip since my last. The subject, 'Lines of Magnetic Force, is one not easily popularised, otherwise, I should like to give you an abstract of it.
Discovery of diamagnetism researches on magne-crystallic action. Faraday's next great step in discovery was announced in a memoir on the 'Magnetic Condition of all matter, communicated to the Royal Society on December 18, 1845. One great source of his success was the employment of extraordinary power.
The singular relations between electricity and nerve-force, relations which it has been attempted to interpret as meaning identity, in the face of palpable differences, require still more extended studies. You may be interested by Professor Faraday's statement of his opinion on the matter.
Faraday's first paper on Magneto-electric Induction, which I have here endeavoured to condense, was read before the Royal Society on the 24th of November, 1831. On January 12, 1832, he communicated to the Royal Society a second paper on Terrestrial Magneto-electric Induction, which was chosen as the Bakerian Lecture for the year.
The ties that bind electricity and magnetism in twinship of relation and interaction were detected, and Faraday's work in induction gave the world at once the dynamo and the motor. "Hitch your wagon to a star," said Emerson. To all the coal-fields and all the waterfalls Faraday had directly hitched the wheels of industry.
Modern physics itself, with the help of Faraday's field-concept, describes these phenomena as caused by pressure resulting from the meeting in space of two similar electrical fields and suction resulting from the meeting of two dissimilar fields.
Modern dynamos range in power from little machines operating machinery requiring only fractions of a horsepower to great dynamos operating street-car lines and lighting cities; but all are built on the same principle as Faraday's rotating disk. By this discovery the use of electricity as a practical and economical motive power became possible.
The singular relations between electricity and nerve-force, relations which it has been attempted to interpret as meaning identity, in the face of palpable differences, require still more extended studies. You may be interested by Professor Faraday's statement of his opinion on the matter.
The Bakerian Lecture, however, has long since passed from the region of pay to that of honour, papers of mark only being chosen for it by the council of the Society. Faraday's first Bakerian Lecture, 'On the Manufacture of Glass for Optical Purposes, was delivered at the close of 1829.
It is an epoch in the life of a young man when he finds himself correcting a person of eminence, and in Faraday's case, where its effect was to develop a modest self-trust, such an event could not fail to act profitably. From time to time between 1818 and 1820 Faraday published scientific notes and notices of minor weight.
