This regenerative process meant that messages could traverse continents and eventually oceans without distortion. By wrapping wire around an iron core and passing current through it, inventors created the muscle that would power the telegraph, capable of pulling a lever or closing a switch at the other end of a line.

Letter Morse Code Letter Morse Code E. The invention of the relay electromagnet solved this problem elegantly.
The core innovation lay in harnessing electromagnetism to transmit coded signals over wires, transforming abstract electrical currents into intelligible messages. Their system, known as Morse code, used a simple on-off keying mechanism to create variable-length sequences of dots and dashes.
Encoding Scheme Optimization for Electromagnetic Telegraphs
Foundations: From Static to Current Early experiments with static electricity proved impractical for long-range messaging due to the inability to regenerate a signal. This variable-length approach was remarkably efficient, assigning shorter codes to the most frequently used letters of the alphabet.
