Why don’t we use magnets to turn turbines and generate electricity?
In: Physics
Magnets are not a source of energy. When two magnets attract each other you need to expend more energy to pull them apart than you could obtain from their movement. When two magnets repel each other you need to expend energy to push them together. You can’t use an arrangement of magnets to make other magnets spin because the magnetic fields as a whole interact with each other, which will result in whatever you’re trying to spin getting locked into place.
When people talk about using magnets as a source of energy they are referring to free energy devices. A free energy device is impossible, it’s not possible to create or destroy energy, only change it’s form.
Captain Disillusion did a video on free energy devices and magnets awhile back with a former TV scientist. [https://youtu.be/sT_bTnkwLuE](https://youtu.be/sT_bTnkwLuE)
