What did Joseph Henry discover?
During his experiments with electromagnetism, Henry discovered the property of inductance in electrical circuits, which was first recognized at about the same time in England by Michael Faraday, who was the first to publish on the subject. In honor of Henry, the SI unit of inductance bears his name.
Who is the inventor of inductance?
Faraday invented the inductor while discovering the phenomenon of electromagnetic-induction nearly two hundred years ago, which subsequently proved crucial for practical large scale use of electricity for power and telegraph communication.
What did Henry Cavendish discovered?
Hydrogen
Henry Cavendish/Discovered
Henry Cavendish was a British philosopher, scientist, chemist and physicist. He is best known for his discovery of hydrogen or ‘inflammable air’, the density of air and the discovery of Earth’s mass.
Who invented the telegraph Joseph Henry?
Morse
Joseph Henry was one of those men. Morse claimed that he conceived of his recording telegraph during an Atlantic crossing in October 1832. By early 1836 he managed to construct a simple prototype, which used a one-element, or quantity, battery and a Sturgeon electromagnet.
What did Michael Faraday and Joseph Henry discover?
Joseph Henry (December 17, 1797 – May 13, 1878) was an American scientist and engineer. While building electromagnets, he discovered the electromagnetic phenomenon of self-inductance. He also discovered mutual inductance, independently of Michael Faraday, but Faraday was the first to publish his results.
Who invented electromagnets?
William Sturgeon
Electromagnet/Inventors
British scientist William Sturgeon invented the electromagnet in 1824. His first electromagnet was a horseshoe-shaped piece of iron that was wrapped with about 18 turns of bare copper wire (insulated wire didn’t exist yet).
Who was Professor Joseph Henry?
Joseph Henry (December 17, 1797 – May 13, 1878) was an American scientist who served as the first Secretary of the Smithsonian Institution. He was the secretary for the National Institute for the Promotion of Science, a precursor of the Smithsonian Institution. He was highly regarded during his lifetime.
Who discovered the makeup of water?
It was the chemist Henry Cavendish (1731 – 1810), who discovered the composition of water, when he experimented with hydrogen and oxygen and mixed these elements together to create an explosion (oxyhydrogen effect).
Who discovered inflammable air?
Sir Henry Cavendish
He is noted for his discovery of hydrogen, which he termed “inflammable air”. He described the density of inflammable air, which formed water on combustion, in a 1766 paper, On Factitious Airs….Henry Cavendish.

Who was Henry Cavendish and what did he discover?
Henry Cavendish FRS (/ ˈkævəndɪʃ /; 10 October 1731 – 24 February 1810) was an English natural philosopher, scientist, and an important experimental and theoretical chemist and physicist. He is noted for his discovery of hydrogen, which he termed “inflammable air”.
What did Joseph Henry discover during his lifetime?
He was highly regarded during his lifetime. While building electromagnets, Henry discovered the electromagnetic phenomenon of self- inductance. He also discovered mutual inductance independently of Michael Faraday, though Faraday was the first to make the discovery and publish his results.
Who was Henry Hudson and what did he discover?
English captain and navigator who discovered the Hudson River, Hudson Strait and Hudson Bay and sailed through parts of the Arctic on his search for a Northwest Passage to China Name: Henry Hudson [hen-ree] [huhd-suh n] Birth/Death: ca. 1565 – ca. 1611
What did Joseph Henry discover about mutual inductance?
While building electromagnets, Henry discovered the electromagnetic phenomenon of self- inductance. He also discovered mutual inductance independently of Michael Faraday, though Faraday was the first to make the discovery and publish his results. Henry developed the electromagnet into a practical device.
