Faraday was a young Englishman with no formal studies but with great experimental talent. He bridged theory and practice, discovering the electric generator, a machine that produces electricity from movement.
And also its counterpart, the electric motor: a device that does the reverse conversion, from electricity to motion. It seems hard to believe, but indeed, the basis of our modern technological and industrial society, even communications and information, all comes from a concept as simple as the following:
The circulation of electrons and the conversion of mechanical movement into electricity, and vice versa.
Let's think about this a little. Let's consider it in a daily setting:
Every day we press switches at home dozens of times and - we get electricity!
We also turn on the washing machine, the coffee maker or the television, with a single click, a simple switch, immediately and with no effort.
It sounds like magic, but it isn't. More than two centuries of inventions, developments and great minds have made this possible. The most wonderful and surprising thing about it is that it is conceptually very simple!
Faraday observed that a magnet rotating inside a cable produces electricity, which is known as electromagnetic induction, or Faraday's law.
