Scientists Find Hole In Earth's Magnetic Field

Velorium writes "The Earth's magnetic field has been found to have two large holes that are making Earth's surface vulnerable to solar winds. Despite what scientists originally thought, these holes allow 20 times the normal amount of solar particles through when they are facing away from the sun. This is the opposite of what the scientists had first speculated."

      Which is somewhat ironic, because the usual way of smelting aluminum generates incredibly big magnetic fields as part of the electrolysis process. I took a tour through a facility once, and there was no limit to the number of paper clips you could stack end-to-end on the tour bus while in the plant. Pretty neat.

      Exactly. The article subject is totally utterly incorect - we have known that Earth's magnetic field has two holes on each pole for decades. It's the very reason that causes Aurora Borealis or the northen lights.

    These aren't unusual, new, or different in any way to what has always happened. Despite the alarmist summary, the point of the article was that more particles sneak through the magnetosphere when the fields of the sun and earth are aligned (opposite to what was believed) and that we had a satellite in the right place to watch this happening.

    No, we didn't cause it. Yes, it's always been happening, but yes we always knew about it. We just had one of the details backwards - more particles get through when the sun and earth fields are aligned rather than opposite, as was previously believed.

    No, it doesn't affect climate change. The repercussions is that the poles get aurorae (revolutionary, I know, particularly as I grew up under them), and that if we get a really bad solar storm with the right conditions it can be bad for the power grid. As has been dramatically demonstrated several times ever since we started building power grids.

    Scientists once believed that the particles entered when the sun's magnetic field was aligned opposite to that of the Earth's. But findings presented at the meeting show that 20 times more solar particles enter the Earth's magnetic field when it is aligned in the same direction as the sun's magnetic field.
