Question

Why don’t we use magnets to turn turbines and generate electricity?

In: Physics

Answer 1

you can. its not 100% efficient though so there are losses, often making it not worthwhile.

how do you move the magnets to induce the electrical current? hence things like water turbines which put simply, use the preexisting flow of water to turn a turbine with magnets on it to induce current.

edit added some extra detail.
