 The Question:
Did William Sturgeon invent the electromagnet? And if so why was
that important?
The Answer:
Yes. William Sturgeon (1783-1850) was a self-educated English
electrical engineer who invented the first electromagnet capable of
supporting more than its own weight. This device led to the invention
of the telegraph, the electric motor and numerous other devices basic
to modern technology.
His invention was a 7-ounce (200-gram) magnet that was able to
support 9 pounds (4 kilograms) of iron using the current from a single
battery. Later in life he lectured at colleges and published the first
English journal devoted to electricity.
