The electromagnet, a magnet whose field appears when current is on and disappears when it is off, was discovered in the 1820s. The American painter Samuel Morse first became acquainted with an electromagnet when it was shown to him by a young chemist he met on a transatlantic ship. Morse realized that a magnet turning on and off by transmission of a current from a distant source could be used to send messages.

He soon enlisted America’s greatest scientist of the time, Joseph Henry, to develop ways to cause an electromagnet to work at a distance. The electric telegraph became truly functional with the idea of using a code of dots and dashes to transmit the letters of the alphabet. Despite this technical help, Morse is given credit for the invention because he put together a practical system and got people to accept it.
