...As the solar flares increase..so does the emission of ions..toward the ea= rth..these charged particles are then influenced by earths magnetic field a= nd 'directed' or steered toward the poles..as these 'streams' of ions flow = toward the earth via the poles..it is like the equivalent of electricity fl= owing through a wire..which of course generates a magnetic field..which var= ies in magnitude in accordance to solar flare activity..the variences in th= is magnetic magnitude is what can overlap..or influence the power grid for = as we know a magnetic field passed over a conductor(power grid) will cause = electricity to flow through the conductor..which can cause a power surge...= it varied enough to black out all of canada down to montreal many years ago= ...look into that for more info... ------Original Message------ From: Mark E.
