Michael Faraday was a 19th-century English scientist known for his groundbreaking work in electromagnetism and electrochemistry. He discovered electromagnetic induction, which is the principle behind electric generators and transformers. Faraday's experiments laid the foundation for modern electrical engineering and technology. In addition to his work in electricity, Faraday also made significant contributions to the field of chemistry. He discovered several chemical compounds and invented the Faraday cage, a device that protects sensitive electronic equipment from external electric fields. His legacy continues to influence science and technology today.
