Scientific Discoveries: A Journey of Serendipity and Innovation

Electromagnetism

In 1819, Danish physicist H. C. Ørsted made a groundbreaking discovery while conducting a classroom demonstration. As he passed an electric current through a copper wire connected to a voltaic cell, he noticed that a nearby magnetic needle deflected. This observation led him to the discovery of electromagnetism, a fundamental principle in the field of electricity.

Excerpt. In 1819 a danish physicist. H. C. Ostered was carrying out an ordinary class demostration. He passed an electric current trough a copper wire wich was joined to a voltaic cell. Amongst the apparatuses on his demostration bench there happened to be a magnetic needle and Oersted noticed that when his hand holding the wire moved near the needle the latter was deflected. With a quick jump of imagination he desconnected the ends of the wwire and connected them to the oposite ends of the Read More
