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.

    Hrm... tinfoil might not be good enough... might even be counter productive. The high energy particles that smack into something in the tin foil would probably generate a spray of secondary particles, all of which would be more likely to smack into something in your brain than the original particle (which would be more likely to pass right through your "me-jelly").

    Physics.

    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.

  12. Re:So what does this mean? by ceoyoyo · · Score: 4, Informative

    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.

    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 being opposite from what the scientists had originally speculated.

    Apparently submitted by the department of redundancy department apparently, the problem is that's not what the article actually says.

    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.

    It the alignment of the fields North-to-South being discussed and nightside effects are not explicitly discussed. Some clarification by a physicist would seem in order.

    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. Here in Northern Europe, which is famous for the display of colorful northern lights, it's actually part of the school curriculum to teach children what physically causes this effect, and even my little brother can tell you that Earth's magnetic field has two huge holes around the poles. The NASA article is about the effects these sun wind particles have on Earth's biosphere.
