Michael Faraday (/ ˈ f ær ə d eɪ,-d i /; 22 September 1791 – 25 August 1867) was an English chemist and physicist who contributed to the study of electrochemistry and electromagnetism. His main discoveries include the principles underlying electromagnetic induction , diamagnetism and electrolysis .
Hertz published his work in a book titled: Electric waves: being researches on the propagation of electric action with finite velocity through space. [134] The discovery of electromagnetic waves in space led to the development of radio in the closing years of the 19th century.
This field emerged in the middle of the 18th century, following electrical researches and the discovery of the effects of electricity on the human body by scientists including Bertrand Bajon and Ramón M. Termeyer in the 1760s, [8] and by John Walsh [9] [10] and Hugh Williamson in the 1770s. [11] [12]
Heinrich Rudolf Hertz (/ h ɜːr t s /, HURTS; German: [ˈhaɪnʁɪç hɛʁts]; [1] [2] 22 February 1857 – 1 January 1894) was a German physicist who first conclusively proved the existence of the electromagnetic waves predicted by James Clerk Maxwell's equations of electromagnetism.
Using his newly developed electromagnetic principle, in 1831, Henry created one of the first machines to use electromagnetism for motion. This was the earliest ancestor of modern DC motor . It did not make use of rotating motion, but was merely an electromagnet perched on a pole, rocking back and forth.
1873 – J. C. Maxwell publishes A Treatise on Electricity and Magnetism which states that light is an electromagnetic phenomenon. 1874 – German scientist Karl Ferdinand Braun discovers the "unilateral conduction" of crystals. [20] [21] Braun patents the first solid state diode, a crystal rectifier, in 1899. [22]
As the field of nanotech grows, the role of nanobots in human bodies will only mature with it, he claims. At some point, the body may become more than 99.9 percent nonbiological.
Bioelectromagnetics, also known as bioelectromagnetism, is the study of the interaction between electromagnetic fields and biological entities. Areas of study include electromagnetic fields produced by living cells, tissues or organisms, the effects of man-made sources of electromagnetic fields like mobile phones, and the application of electromagnetic radiation toward therapies for the ...
