The Connection Between Magnetism and Electricity

In 1820, Hans Christian Ersted connected a copper wire to a voltaic pile and when the current flowed, the magnet began to swing perpendicular to the current. Within weeks, the information reached Paris where Amper and Arago showed that if you want the current into a coil, it behaved just like a magnet. A few weeks later, Michael Faraday makes the first rudimentary electric motor. The electromagnetic revolution spreads like wildfall. And what about the question of radio, though? Because radio is also electromagnetic radiation. Now is the connection made between electricity magnetism and then transmitting invisible waves and information that way? Well, that was really thanks to Maxwell, who developed a unified theory of
