Yes, the original telegraph used electromagnets (a magnet created by passing current through a wire wound around a piece of iron) on the receiving end. The sending end did not require magnets but the device that made the clickety clack sounds on the receiving end was an electromagnet pulling two pieces of metal together.
Before the telephone, telegraphs were used.

Lead is used in magnets.
Lead is not typically used in magnets. Magnets are usually made from materials such as iron, nickel, and cobalt. Lead is not a magnetic material and is not commonly used in the production of magnets.
The Telephone had not been invented and telegraphs lines could be taped and taped to send messages by an army in the field and where much faster then when sent by horse.
Yes, they were used. However, they did not play a significant role in WWI. Hope that helps!
