Michael Faraday was a British scientist born on September 22, 1791. He is best known for his groundbreaking work in the fields of electromagnetism and electrochemistry. Faraday discovered the principles of electromagnetic induction, which explains how electric currents can be generated by changing magnetic fields. His experiments laid the foundation for many modern technologies, including electric generators and transformers. In addition to his work in physics, Faraday made significant contributions to chemistry. He discovered several chemical compounds and invented the Faraday cage, a device that protects sensitive electronic equipment from external electric fields. Faraday's legacy continues to influence science and technology today.
