Example Sentences
Recent Examples on the Web The researchers tested their method by storing one of 19th-century physicist Michael Faraday's seminal papers on electromagnetism and chemistry, as well as a JPEG image of Faraday. 
Jennifer Ouellette, Ars Technica, 8 Aug. 2022 Wireless charging is an extremely competitive concept, with multiple start-ups vying to transmit power via electromagnetism, lasers or sound waves. Sophie Bushwick, Scientific American, 2 Sep. 2021 The components of electromagnetism are thus quantum in origin. Sumeet Kulkarni, Los Angeles Times, 2 July 2022 Now physicists seek a single theory that fuses general relativity, which describes gravity, with quantum field theory, which accounts for electromagnetism and the nuclear forces. John Horgan, Scientific American, 25 June 2021 These use electromagnetism to directly heat up a pan, rather than getting an element hot through electrical resistance and then heating up the pan that way. Ryan Cooper, The Week, 14 Sep. 2021 There are fields associated with fundamental particles like electrons and quarks, and fields associated with fundamental forces, like gravity and electromagnetism. Quanta Magazine, 24 June 2021 Some physicists insist that everything, including humanity, is ultimately explicable in terms of particles pushed and pulled by gravity, electromagnetism and other forces. John Horgan, Scientific American, 3 Sep. 2021 Gauge theory had been developed in the 19th century by James Clerk Maxwell, a British physicist, in his seminal work to explain electromagnetism.
