It's flipped 7 times in the past 2 million years. The problem is while it's flipping, we will all be exposed to increased radiation.
{quote]Historically, Earth’s North and South magnetic poles have flipped every 200,000 or 300,000 years—except right now, they haven’t flipped successfully for about 780,000 years. But the planet’s magnetic field is at long last showing signs of shifting. Although there’s no way to know yet for sure, it could be gearing up to flip once more, according to Undark Magazine. And that possibility is raising new speculation about what that means for planetary life.
Our planet’s magnetic field protects us from lethal levels of radiation from phenomena like solar rays. The dangerous particles never hit us directly, because upon entering the Earth’s atmosphere the magnetic field deflects them and forces them to move around, according to NASA. So the prospect of that field weakening, which it does when it’s getting ready to flip, is worrisome: It would leave us without sufficient protection.
