No really in present day & apart from a few experiments...nothing in practical use...in the future - very likely...
Here's something u may like to read in relation to a similar topic. A scientist by the name Nikola Tesla which I'm sure you'll find very interesting. Have a look on the net or the book-the man who invented the 20th century.

I think that it might be possible, but you would have to overcome perpetual motion first. The reason is that the magnetic force is so small, compared with the friction in an electric motor or generator that it would not turn. Which are at the most only 78% efficient.

Technically a compus needle moves because of the earth's magnetic field. You might be able to build some contraption that can get the tiniest amount of energy out of the movement of a compus needle but what's the point? The magnetic field is so weak, there's no use trying to get any kind of energy out of it.

possible... as long as you can tapped the energy and have the technology to convert them to run electric motors...

Sure, they've run this experiment with the Shuttle, using a tether suspended from the Shuttle.

i don't know any direct methods...
but heard of a system called gravity-wheel it can be used to produce electricity. but it is still under research.
