Cruickshank and the first flooded battery? Cruickshank and the first flooded battery? The third method of generating electricity was discovered relatively late — electricity through magnetism. In 1820, André-Marie Ampère (1775-1836) had noticed that
wires carrying an electric current were at times attracted to one another, while at
other times they were repelled.
In 1831, Michael Faraday (1791-1867) demonstrated how a copper disc was able to
provide a constant flow of electricity when revolved in a strong magnetic field.
Faraday, assisting Davy and his research team, succeeded in generating an endless
electrical force as long as the movement between a coil and magnet continued. The
electric generator was invented. This process was then reversed and the electric motor
was discovered. Shortly thereafter, transformers were developed that could convert
electricity to a desired voltage. In 1833, Faraday established the foundation of
electrochemistry with Faraday's Law, which describes the amount of reduction that
occurs in an electrolytic cell. In 1836, John F. Daniell, an English chemist, continued with the research of the
electro-chemical battery and developed an
improved cell that produced a steadier current than Volta's device. Until then, all
batteries had been composed of primary cells, meaning that they could not be recharged.
