Gravity & Magnetism: Generating Electricity?

[atal]

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.
