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

Question

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

In: Physics

Answer 1

Perpetual motion (infinite energy) is currently impossible because we haven’t found any exceptions to the first law of thermodynamics (no energy can be created destroyed).

So the energy a magnet gives off can’t create electricity (at least in the way the question is stated)
