It's caused by volcanos in your nose.

They have an electro-magnetic effect, cause power outages by inducing over-current situations. Movement of the ionosphere, as well as currents within, which can be caused by solar ejections and other things (induced EMP), induces currents into powerlines. These currents induced into powerlines cause the cores of transformers to saturate and greatly increase the third harmonic of the 60 Hz waveform. This third harmonic changes the waveform from a sinusoid to a non- montonic rounded spike whose total voltage component is greater than the 60 Hz, which causes overloads in the transmission system. If the sun spewed a steady stream of particles there would be little or no induced currents as, from Gauss's Law, it is the time change in flux density that causes the time rate change of current in a closed conducting loop. The change in flux due to the earth's rotation through the particle stream may induce currents, but not to the scale of a moving ionosphere. Are the currents induced on the power lines as result of magnetic or electric induction? Properly laid out powerlines reverse the twin lead periodically (as in twisted pairs) to decrease the magnetic induction. The lines are generally laid out orthognal to the electric field of the earth. Particles would have to pass between the power lines or strike them (in an overwhelming majority of one polarity) to induce blackouts. I think it's all caused by hair stylists. |
