Heinrich hertz contribution

Pioneer of electromagnetism, motors, generators and telegraph, The accomplishments and life of Joseph Henry, Jr. Joseph Henry and Michael Faraday are the founding fathers of the electrical industry and electrical technology. Electric motors, generators, transformers, radio and the telegraph all function on electromagnetic principles discovered by these men who worked on opposite sides of the Atlantic.

Henry not only pioneered electrical technology almost 50 years before Thomas Edison, but led the Smithsonian, National Academy of Science and occupied important positions such as President Lincoln's science advisor. The world of physics and electronics now uses the scientific unit "Henry" H to measure inductance. Henry is the founding father of the National Weather Service and led study of the atmosphere.

How did joseph henry die

Using a relatively stable battery to supply current creates a flurry of discoveries. When he energized it became magnetized for a moment, then lost magnetism when the current escaped into the iron core. He could not do a multi-layered wrap, which did not allow the magnet to be very strong. The electromagnet has remained basically the same ever since.

Princeton funds a trip to England where Henry meets his contemporary Michael Faraday. Faraday's work is based on moving a copper wire relative to a stationary magnet, Henry's work is based on using electricity to create a powerful electromagnet, which induces current in a second electromagnet, and electricity is than created on the other side this is the basis of a transformer.
