Gravity & Magnetism: Generating Electricity?

AI Thread Summary
Gravitational acceleration alone does not provide sufficient velocity for a ferromagnetic coil and magnetic field interaction to generate sustainable electricity. While lifting a magnet and allowing it to fall through a coil can produce some energy, it yields less energy than the input required to lift the magnet. The concept of free energy or perpetual motion is dismissed, reinforcing that energy cannot be created from gravity in this manner. Overall, gravity cannot serve as a reliable energy source for electricity generation. The discussion concludes that the principles of energy conservation apply, negating the possibility of perpetual motion systems.

Is gravitational acceleration, g, at any given spot around the globe imparting sufficient velocity so that the interaction (interchangeable) between a ferromagnetic coil and a magnetic field may generate electricity?

It would not be sustainable in terms of an energy source. If you lift a magnet up and let it fall through a coil, then gravity will be generating some energy, but less than what you put into the system to lift up the magnet in the first place.

There's no free energy, and no perpetual motion.
 
Thread 'Motional EMF in Faraday disc, co-rotating magnet axial mean flux'
So here is the motional EMF formula. Now I understand the standard Faraday paradox that an axis symmetric field source (like a speaker motor ring magnet) has a magnetic field that is frame invariant under rotation around axis of symmetry. The field is static whether you rotate the magnet or not. So far so good. What puzzles me is this , there is a term average magnetic flux or "azimuthal mean" , this term describes the average magnetic field through the area swept by the rotating Faraday...
