James Clerk Maxwell (1831 - 1879) was a Scottish scientist who is most famous for his classical theory of electromagnetic radiation, which for the first time brought together electricity, magnetism and light as different manifestations of the same phenomenon.This unification by Maxwell is considered a scientific landmark comparable to the work done by Isaac Newton and Albert Einstein. In 1850 he went to the University of Cambridge, where his exceptional powers began to be recognized. Assuming light to be the manifestation of alterations of electric currents in the ether, and vibrating at the rate of light vibrations, these vibrations by induction set up corresponding vibrations in adjoining portions of the ether, and in this way the undulations corresponding to those of light are propagated as an electromagnetic effect in the ether. He left a detailed account of his research under the title of Experiments on the Origin of Electricity. For experiments, he initially used voltaic piles, but later used a thermocouple as this provided a more stable voltage source in terms of internal resistance and constant potential difference. Touching the iron nail accidentally with his other hand he received a severe electric shock. In fact, tourmaline remains unelectrified when its temperature is uniform, but manifests electrical properties when its temperature is rising or falling. Brush's Windmill Dynamo', Scientific American, vol 63 no. "FARADEI, GENRI, I OTKRYTIE INDUKTIROVANNYKH TOKOV." He therefore contended that in the charging of a condenser, for instance, the action did not stop at the insulator, but that some "displacement" currents are set up in the insulating medium, which currents continue until the resisting force of the medium equals that of the charging force. The resistance of the dielectric is of a different nature and has been compared to the compression of multitudes of springs, which, under compression, yield with an increasing back pressure, up to a point where the total back pressure equals the initial pressure. Noyce's chip solved many practical problems that Kilby's had not. The electric machine was subsequently improved by Francis Hauksbee, his student Litzendorf, and by Prof. Georg Matthias Bose, about 1750. Two parallel portions of a circuit attract one another if the currents in them are flowing in the same direction, and repel one another if the currents flow in the opposite direction. If on the other hand the needle is fixed it will tend to retard the motion of the disc. Who was the first scientist to believe in the electromagnetic theory? Famous Physicists - List of World Famous Physicists [44][45] In 1749, Sir William Watson conducted numerous experiments to ascertain the velocity of electricity in a wire. Science and the scientific method: Definitions and examples This was connected with the electron theory developed between 1892 and 1904 by Hendrik Lorentz. Democritus was the world's first great atomic philosopher. Peltier in 1834 discovered an effect opposite to thermoelectricity, namely, that when a current is passed through a couple of dissimilar metals the temperature is lowered or raised at the junction of the metals, depending on the direction of the current.
