The solar wind interact with the Earth's magnetic field and induces electric currents in the upper atmosphere [aurorae] and in pipelines on the ground, and in seawater, and in rocks deep underground. Thanks Dr Svalgaard, And that all ?Why no more ? Particles or trade winds ? Rossby waves ? because these have not been convincingly shown to be influenced by solar activity. |

And for the daily solar disturbances, what about aurorae and pipelines for example ? France basic physics has proven that when you move a wire, or for that matter any piece if metal, through a magnetic field the motion induces an electric current in that wire. In the case of a Solar Wind/CME the metal pipe stands still but the magnetic field moves through it. It's the same principle. |

I agree with this explanation, but should add : also Earth is moving ( rotating around it's axis and around Sun.....) so it is also a relative moving of grid, pipes... to newly changes in magnetic field which itself is moving... Everything in space is relative and moving. |

I'm sorry but everyone knows "trade winds" are influenced by solar rays and for particles it's like Kevin explained and Purinoli completed n the case of a Solar Wind/CME the metal pipe stands still but the magnetic field moves through it. It's the same principle.Everything in space is relative and movingpipeline or any particules it's the same all over the Earth. This it's explain both with Krups Moulinet (I don't know the american word), sorry for the "mot du jour) and Maxwell equations the first showing the effect the second giving the scientific equation.  |

A "Krups moulinet" is a _coffee grinder_, 'Krups' being a manufacturer of such appliances and 'moulinet' being the diminutive form of 'moulin' (mill), so 'little mill'. Merci, encore une fois, pour le mot du jour!
But you're overlooking the fact that ground coffee is not electrically charged, so when you hurl the ground coffee through space, the solar and terrestrial magnetic fields have no discernible influence on them.

Faraday's Law. We're overlooking another important law, Ampere's Law, which states that moving charges produce a magnetic field. So the moving charges inside the Sun, the solar wind and inside the Earth, all generate the magnetic fields we are talking about.

sorry John af4ex "moulinet de Krups" isn't an appareil for coffee but an astrophysics tool. Maybe it could be translated by "Krups reel" it moves only when light striks on the metal  (I was wrong on my last message, Bob wrote the phrase not Kevin) |

I'm looking for but not easy to find something. Here the image it's a begining  yes it is the Crookes radiometer I was wrong with the name.  |

>> yes it is the Crookes radiometer ... I had one of these gadgets when I was a kid (way back in the last millennium). They were once commonly found in toy stores. Haven't seen one in many years. According to Google, the exact principle of operation is still in dispute: en.wikipedia.org/wiki/Crookes_radiometer |

well, I am not selling, but a website that is pretty cool is - there is also an explanation of how they think it works.

Thinkgeek.com is a very cool website. Alot of toys I would like on there.

Any chance 1101 is cycle 23 - jk? Magnetic and near the equator just seems odd. Is it more likely that reverse polarity sunspots are near the equator?
