I think the MoD have a say in the locating = of Wind=20 Turbines owing to there effect on RADAR but nothing to do with stray = magnetic=20 fields as far as I am aware.

Surely if the magnetic field leaked that much, the generators = would=20 suffer efficiency.  
They are designed as closed magnetic circuits, with all the field = lines=20 closely confined in iron, with small air gaps
