Shoulders of giants.
Faraday was the first to demonstrate an actual physical process where electrical energy was converted to mechanical energy.
It's turtles all the way down.

In the early days of electricity research, static electricity was more common than "current" electricity. There were early static-based telegraph experiments that predated Morse [2] and used a silk thread as a conductor. Before the electromagnet was invented, people didn't know how to build an indicator based on electric current - one concept was to use electrolysis and look for bubbles.

Its such a simple thing but no one had thought of a reason to do such a thing.
What happened to the compass shocked the world and triggered Faradays many beautiful experiments.
