The Power of Electricity and Magnetism

You are controlling invisible forces every time you flip a switch. Electricity and

magnetism aren't just separate chapters in a textbook, they are actually two sides of the

same coin. It started with ancient Greeks finding magnetic rocks, but geniuses like

Nikola Tesla turned it into the world we know. Here is the mind-blowing part.

If you move a magnet near a wire, you create electricity. That is a generator. If you feed electricity

into a magnet setup, you get movement. That is a motor. Whether it is your car or your toaster,

you are just manipulating magnetic fields to do your heavy lifting.
