Seems unlikely that the magnetism would reach
that far to me - the magnetic field would be no different to any other large
generating set - they are just an ordinary alternator driven through a
gearbox.
If they did affect magnetic compasses you would
have thought that the place you would really notice it would be around the
coast, with small boats sailing in amongst them.
Although they look as if they are turning
slowly, they can't do many rpm before the tips of the blades go supersonic,
as the blades are many 10s of metres long.
Over what distance did you notice the
magnetic effect? perhaps I could get down to the ones on Romney Marsh,
here in Kent and see if they have any effect on a compass
needle.
The moving blades can affect radio reception
for people living nearby, although I've not noticed this
myself.

Great for LF!!!!!!!!!!!!!
Experience
Driving to Gleneagles in Scotland last weekend my
car magnetic compass was reading backwards and erratic and I wondered
why.
The hills es mountain tops are covered with WIND
TURBINES, hugh beasts and only turning slowly, cannot be producing
much electric.
however thinking about it I have concluded that the
strong MAGNETS in the turbines must effect a magnetic
compass, possible aeroplanes as well except they are flying
very high, might also have an influence on GPS frequencies and
navigation in these areas
I must say these hugh Monsters strewn all across the
Scottish mountain tops and countryside spoils the
scenery.
