In the early 19th century, a scientist named Michael Faraday discovered a fascinating connection between electricity and magnetism. This connection, now known as electromagnetism, is a fundamental concept in physics and has revolutionized technological advancements in our world. Electricity and magnetism are not separate entities but two sides of the same coin. When an electric current flows through a wire, it generates a magnetic field around it. Conversely, a changing magnetic field can induce an electric current. This fascinating interaction is known as electromagnetic induction. Perhaps you've noticed electromagnetism at work in your daily life. See your smartphone? It receives calls and texts through electromagnetic waves. The loudspeaker that amplifies your music? It's driven by electromagnetism. Even the high-speed maglev trains in some countries float above the tracks thanks to powerful electromagnets. Understanding electromagnetism opens doors to a deeper understanding of the world around us - a world driven by the invisible, yet powerful, forces of electric and magnetic fields.
