What is Hans Christian Ørsted famous for discovering?

I am known for my discovery in 1820 that electric currents produce magnetic effects. While investigating a voltaic pile, I observed that the needle of a compass deflected when an electric current was switched on or off nearby. This finding demonstrated a direct connection between electricity and magnetism, a force previously thought to be separate. This observation was crucial in establishing the field of electromagnetism and showing the interconnectedness of seemingly disparate natural phenomena.
