Hi all
 
I think the MoD have a say in the locating of Wi= nd Turbines owing to there effect on RADAR but nothing to do with stray mag= netic fields as far as I am aware.

I think  there  are  some p= roblems  with  walking  in Scotland  using   = magnetic  compasses  , due to the  rocks ??

Surely if the magnetic field leaked that much, the generators would su= ffer efficiency.  
They are designed as closed magnetic circuits, with all the field line= s closely confined in iron, with small air gaps

Great for LF!!!!!!!!!!!!!
 
Experience
 
Driving to Gleneagles in Scotland last weekend my c= ar magnetic compass was reading backwards and erratic and I wondered why.
The hills es mountain tops are covered with WIND TU= RBINES,  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 compa= ss,  possible aeroplanes as well except they are flying very high= , might also have an influence on GPS frequencies and navigation in th= ese areas
I must say these hugh Monsters strewn all across th= e Scottish mountain tops and countryside spoils the scenery.
