Who invented the dynamo?


Quick Answer

The first dynamo was built by Hippolyte Pixii in France in 1832, and was based in part on the work completed in the 1820s by Joseph Henry and Michael Faraday, who discovered and analyzed electromagnetic induction. A dynamo is a device that uses electromagnetism to to create a direct current of electrical power. It is also known as a generator.

For humans to be able to use large amounts of electricity, they must use have dynamos, alternators (sometimes also called generators) and batteries. It took more than 50 years after the first battery was created for a person to create a working dynamo due to the complex field of electromagnetism.

Although Pixii had created the first dynamo and the first alternator, he was not able to use his dynamo effectively. Many other scientists contributed to the field, such as Antoni Pacinotti, Werner Von Siemens, Charles Wheatstone and Zenobe Gramme, but it was not until 1876 that the dynamo was ready for consumer use. In 1876, Charles F. Brush of Ohio designed a reliable dynamo that was then sold by the Telegraph Supply Company.

Dynamos are used today to run powerful generators at factories and industrial centers worldwide, as well as powering home generators for individual consumer needs.
