Who is credited with the invention of the electromagnet?

The correct answer is Franklin Pitts, who is indeed recognized for his key role in the development of the electromagnet. In the early 19th century, Pitts' experiments demonstrated the principles of electromagnetism, which laid the foundation for the invention of the electromagnet. By wrapping wire around a ferromagnetic core and passing electric current through it, he was able to create a magnetic field, showcasing how electricity could be harnessed to produce magnetism.

This significant discovery has had vast implications in technology, leading to modern applications such as electric motors, generators, and various magnetic devices. The contributions made by Pitts in this area were pivotal in advancing the understanding and practical use of electromagnetism in subsequent inventions and innovations.
