Why does this LED light up? Magnet + coil = AC electricity! #ElectromagneticInduction #ACPower #STEM

This simple experiment shows how electricity is generated without a battery—using only a magnet, a coil, and motion ⚡
I first move a neodymium magnet left and right near a coil connected to an LED. The LED lights up because a changing magnetic field creates alternating current (AC).
Then, I rotate the rotor disk of my axial flux wind turbine and bring the same coil close to it. Once again, the LED turns on—proving this is the exact principle used in real wind turbines and generators.
No theory slides.
No simulations.
Just real physics, real experiments, and real results.
If you want to truly understand:
How wind turbines generate electricity
How AC current is produced
How axial flux generators work at low RPM
And how to build DIY renewable energy systems
