Michael Faraday built the first primitive electric motor in 1821
A current-carrying wire rotating around a magnet demonstrated electromagnetic propulsion
English scientist Michael Faraday constructed a homopolar motor in 1821 by suspending a copper wire in a dish of mercury containing a permanent magnet. Passing electric current through the wire created a magnetic field that caused the wire to rotate continuously around the magnet. This experiment demonstrated electromagnetic rotational motion, laying the foundation for electric motor technology.

Michael Faraday built the first primitive electric motor in 1821: the short answers
- Where does this come from, and can I check it?
- A current-carrying wire rotating around a magnet demonstrated electromagnetic propulsion. The figure is taken from The Royal Institution, which is linked in full on this page. Every fact on Mondo Knows names its source rather than repeating an unsourced claim.
- Is this really a technology fact?
- Yes. It sits on the Technology shelf, one of 1,090 sourced facts grouped into space, animals, the human body, history, science and more. Category pages collect every fact in the same field.
- What else can I read about it?
- The links under the fact point to a quiz, game, puzzle or calculator on the same subject, and the shelf below shows related facts. The wording here is original, and quoted phrases are marked as quotations.
