Ancient Jars Hold Clues About Earth's Fluctuating Magnetic Fields
www.nytimes.com/2017/02/14/sc...
"Geoscientists have little knowledge of what has been occurring with the magnetic field during recent millenniums. The current decline could be just a squiggle of typical fluctuations. So they turned to pottery and the record keeping of ancient bureaucrats."
Why Earth's Inner and Outer Cores Rotate in Opposite Directions
www.livescience.com/39780-magn...
"Scientists have long suspected that Earth's magnetic field - which protects life from harmful space radiation - drifts in a slightly westerly direction. That theory was established in the 1690s, when geophysicist Edmund Halley (the same Halley who spotted the eponymous comet) sailed aboard a research vessel through the South Atlantic Ocean and collected enough compass readings to identify this shift."
You might still be a simple bacterium, if not for magnetism
www.washingtonpost.com/news/s...
"Scientists think that about 500 million years ago, Earth's core solidified, turbocharging our magnetic field. This would have allowed the atmosphere to hold more gas, in part shielding early life from powerful solar rays - and allowing multicellular life to evolve."

It is my understanding that during a flip, the poles break up, resulting in many poles with a much weaker total magnetic field. While the field is weak, the earth becomes vulnerable to a solar mass ejection. During this period the earth's atmosphere will become highly ionised, blocking radio communication and possibly ending our technology based society. it would be interesting to know if there is any correlation between any mass extinction events, paleo gamma luminescence and the Earth's magnetic field reversals.
Pole Shift is a lie
Because Earth has no magnetic poles.
Magnetism is the only force that decays at distance cube.
If the hypothetical magnetic pole of the earth is 0.6 Gauss, how can there be a magnetic field of 0.2 Gauss at the equator? It's impossible.
Sunlight moves westward around the Earth, creating a weak current that causes compass needles to point north. Due to the smaller circumference, this weak current becomes stronger near the poles, producing auroras.
Only if Earth spins the other direction, then compasses will point to south. It will not cause any danger at all.
@@ScienceBusted the geological record traps the status of the earth's magnetic field as lava at the constructive plate boundaries cool and solidify.
This record clearly shows the the Sarah's magnetic does periodically reverse. This has not happened in the history of the human race.
As the earth's magnetic field is responsible for maintaining the protection of the atmosphere from cosmic rays, it seems reasonable to ask what will happen during the period where the field becomes chaotic and potentially falls to zero. Without the fields protection, a solar mass ejection directed to earth would have nothing to stop its interaction with our atmosphere.
Add to this that solar output has increased over the years of earth's history.
It is reasonable to argue that the coincidence of an earth directed SME, with a zero in the earth's magnetic field maybe responsible for at least one extinction level event in its history.
The mechanisms for the generation of the earth's magnet field is well understood, it being produced by rotation of the planet's molten iron core.
Experiments that emulate this effect have shown such a generation process is unstable and can be subject to periodic pole reversals of the field. During the periods of weakened field, prior to a reversal, the predominant north and south pole may break up into multi-poles that can appear at lower latitudes. Thinking about the churning and chaotic motion of the iron core, it is not hard to imagine how this might happen.
@@nigeljohnson9820 BS. 0.6 Gauss imaginary magnetic field cannot magnetize rocks.
When Earth's magnetic field finds out about this, Earth's magnetic field is going to flip.
Good Kid M.A.D. City lol good one😂😂😂😂

The Milankovitch cycles cause climate change, Obliquity causes Global warming due to increased Direct sunlight at higher latitudes. Precession causes Global Tsunami's when the equator eclipses the orbital plane at he equinoxes. The last equinox was 12 k yrs ago when Gobekli tepe was filled in by sediment from the tsunami, Eccentricty is the trigger at perihelions.
Covid is a LIE built on the Baby Boomer Bust due to the usual suspects of seasonal FLU and old age.
@@GregoryJByrne people like you are the reason why almost 2 million people are dead
And when the earth flips the sun will rise from the west which us Muslims are already informed of and also its going to happen soon as all the prophesies prophet Muhammad sed that will happen b4 judgment day have come and are going to happen!
@@bossniko9585 I am not trying to disrespect you, but I imagine that in prior full reversals the sun has rised from the west for several million years
I love science. I love all of you beautiful people. Have a nice day wherever you are on the planet :)
Gerhard Veldman same to you, mate!!
Gerhard Veldman nl?
Serial NetherLands
Gerhard Veldman I'm jk love u
same to you dude.
For those who don't know, the magnetic north pole is in fact the south pole of the earth's magnet. That is why the north seeking end of a compass needle (which actually is the north pole of the magnetic compass needle) is attracted to the earth's magnetic north pole (which as stated is the south pole of the earth's magnet). The south magnetic pole of the earth is similarly the north pole of the earth's magnet. Dissimilar magnetic poles attract.
Dnews sounds better because it has D in it
screamowaffles Durh News
DickNews a news with balls
screamowaffles duhh news, cause you say duhh so often wh3n u watch it
screamowaffles *AirAirAirAAAAAIIIIIIRRRRHOOOOORRRRRN*
Everything's better with a nice D in it.
The magnetic field itself is no big deal but.. Its all the mega earthquakes and volcanoes you have to worry about.
Guided Meditation And solar radiation as the field will be weakened by the flip.
So we will be followed by a frying pan sun?
Feel sorry for the people who bleach their skin!
Guided Meditation animals use the magnetic field to navigate, a lot of animals will die, that is one of the effects.
The magnetic field is reacting to those earthquakes & volcanic eruptions. We have stripped the earth of the metals that hold the magnetic field on place. It's just searching for a high metal ore deposit, as we've stripped it all.
Look on the flip side everything will be fine.
Oh my god. You're so punny.
Christian Gonzales I'm attracted to good humour
Mi Les
Then what the hell are you doing here ???
👏👏👏
...great vid and all, but whats with the channel name change?
The Green Men dont know
They explained it on the previous video. They got partnered with a different company, and changed the name accordingly.
ah, Ok
And I was already starting to question the reliability of my memory...
NateDevine the name sucks lol
So could this be a potential reason explaining the cooling and heating of the earth naturally over time?
but the earth is flat and the sun is only 3,000 miles above us
Cisco G The earth is only 2017 years old too
Gangyi Xu yes couldn't believe when I first heard. there is also no gravity on earth only a force that pushes upward on this flat earth we live on.
Isn't it amazing what these hip-hop artist and basketball players have discovered.
Hræð Van De Gevel The Earth is approximately 4.54 billion years.
What's with the flat earthers meme. It's 2017's Harambe or something?
I was receiving notifications from this "seeker" channel without realizing it was you guys. Great video!
I was trying to explain this to someone...they didn't believe it was possible for the pole to ever change.. idk why they thought this and why they were so close-minded when I tryed explaining it
"Exact magnetic north has moved further north." If any sentence is going to mess up you mind, this one is that one.
3.14159265 to 3.141592653589
if the magnetic field does flip, it should take a while to do so, like maybe a few years at most. In that time, the Auroras that occur at the ends of the magnetic field will be visible from places that don't see them, say Hawaii or Arizona. Imagine what a sight that would be, the northern lights dancing on a tropical beach or over the Grand Canyon.
I'm a physicist, and trust me when I tell you we could use as much help from anyone out there as we could possibly get, and I'm not referring to funding oh, although that's nice too. I'm relating this to all future and Junior physicist. Endeavor to persevere young physicist Endeavor to persevere.
As always, very well presented and easy to understand. Nice one Trace 🏆👍🏼😊
*"Seeker"* ??? What did I miss ?
FRPlayerOne Mandela Effect...
Hræð Van De Gevel they were dnews before
You missed a video where they explained it lol.
Hræð Van De Gevel no, no they werent
Some Larry guy linked the video about Pluto, where they explain this change at the end. But the comment has been automatically flaged cause of the link. Anyway thanks to him.
It would have been clearer if they explained the change in a specific video, rather than 20 sec at the end of a random video...
I actually watched the Pluto video, but I always skip the end speech lol
When Magnetic Poles flip occur the field is weakened slightly, this makes cancer slightly more common
You need to update this, instead of saying nothing will happen when it flips, you should tell everyone that each time it did flip resulted in the "end of the world" to put it nicely....
Great breakdown of the process, Trace!
The Quality of this video is better than usual. I don't know what but it's just good. Also can I have the music it fits so well. Would love to listen to it in my own time.
I don't mind the name change and I'm still a big fan of this show and everything, but I always loved the zany, excited about science feel this channel had and I feel like the new look, music and even (very surprisingly calm) Trace's presentation makes it feel less exciting and more serious...
Cause it is more serious.
wasn't it the ancient paintings in the caves that kind of indicated that the magnetic field has flipped?
finally, mainstream coverage on the topic!!
A question, if the magnetic field is moving, could this affect the earths rotational axis?
Wait... So this means Australia will be right side up soon?!
yeah, i guess we'd have to call it the up-over....
john11719 well it is and it isn't. It's all about your perspective.
Yep we'll be soon upside down...
So one thing I've always wondered is when the poles flip does it become an invert or a mirror image? Basically does East and West Flip too?
This does not mention the polar shift records on the ocean floor away from the mid oceanic ridges. The US Navy mapped this phenomenon during and after WW2, and couldn't make sense of it. However, this became key in verifying plate techtonics and continental drift.
It is also one of the tools that geologists have at their disposal to date and place land masses throughout the geologic history of this planet.
Does temp affect the magnetic 'setting' of the pottery? Because, even if manufacturing processes remain the same, fuel sources would change over the centuries. In a given area you might use one type of wood for a few years then switch to another. This would create a slightly different make-up of the end product. Might even cause the pottery to set before the magnetic particles have had time to orientate themselves.
So the field won't just like... Snap instantly during the switch. Is there anything we could expect to happen during that in between time? Like increase in solar radiation that reaches the surface of Earth, or anything like that? Thanks for the video!
Dogs meowing, cats barking, cows braying, donkeys mooing, the whole words gone crazy!!!!!
Kind of emphasizes how important preservation of archaeological sites really is, and amplifies worries that wholesale destruction of them through war, looting, or corporate sabotage (like how the DAPL bulldozed hundreds of sacred sites) can damage evidence for future discovery.
Look at recent news about how fast both the North and South Magnetic Poles are moving at rate of ~55 km year in approximately the same direction for decades now. Plots of both poles suggests a pattern of accelerated pole movement consistent with pole flipping and we may have been witnessing that periodic flip as it evolves for the last few decades.
Doomed
How are we looking on those poles now ya think??
I almost didn't click on this video because I didn't see DNews on it lol
i went to a university's lecture about this 2 weeks ago its amazing
I wish I had a teacher like this guy. In my school the teachers teach properly but sometimes we do not understand. I understand all the topics that this guy says in the videos....
Why are we using Coal to generate energy , when we can use Earth's Core Heat (or even by Lava) by developing a feasible technology
Balaji Chandrasekaran Why question it on the Internet when you could be out creating this technology and saving the world?
Balaji Chandrasekaran We already do this. It's called geothermal.
Most of Iceland, and some of Sweden and Finland use it in some form or another as far as I know.
The main limiting factor of geothermal is that you need to build plants very close to a heat source. Most of the earth is not in close proximity to a heat source.
Look up a tectonic plate map, the borders are areas where geothermal power could be used.
Because Earth's core is unreachable. And as for lava, I think there might actually be some people out there already trying to figure that out...
Imagine a Digging project @ Mariana Trench (11km below sealevel + Deepest hole dug by mankind 12km ,+ Xtra 7km is enough to reach below the crust ~1000.C heat Source from upper mantle is enough 2 run A FLOATING GEO THERMAL plant @ midddle of Ocean
( I guess this sounds sci-fi type)
Balaji Chandrasekaran I don't think you can dig 12 km at Mariana's trench, the 12 km limit was due to the drilling device melting and/or getting stuck in gooey rock, so maybe digging at the trench you can get some extra 1 or 2 km, but the same problems will appear.
But the clay from the Iron Age kingdom of Judah, 800-200 BCE doesn't help us out in any way to narrow down the date of the last magnetic pole shift 785,000 years ago; nor does it help us predict the next one. So that factoid is irrelevant.
Yeah getting an idea of the position of true north at different times throughout Earths history will not help at all in understanding the magnetic pole shift. Where do you idiots come from.
Yeah but wouldn’t they be able to nail down when the last few happened and matching that time frame with local and worldwide events at those times and gain some incite into what are common occurrences during a pole reversal and how long they last ?
This video would've been very useful 4 months ago when i was studying geology in school.
If the earth's EMF is generated by the core spinning, wouldn't the core need to spin in the opposite direction to flip of the field?
Why hello there person, have a nice day!
WolfyWolfGaming u too!!
Alexandra the Phanchild u too!!
Alexandra the Phanchild you Aswell
This is what's happening now.
Correct! See 'Maverickstar reloaded' channel for regular updates.
I have just one thing to say to this.... Thermal Annealing: An Effective Process to Enhance the Performance of Magnetic Devices and Materials.
Could they be wrong and it is possible they changed the temperature and process of baking the clay pots over time and this resulted in a change to the magnetic properties of the clay in the pots in the same way Annealing does?
It flips every 12000 years and we’re due
If they switch, wouldn't it also extinct many animal species like Butterflies, Whales, Birds and other animals that use the magnetic fields to locate themsleves
ZDavePlays Haven't those creatures been around for a magnetic switch, meaning they know what to do? But even if they haven't, They probably would be evolve to know what way to go again.
ZDavePlays No. they'll be fine. They'll just have to yell Marco!!!! Polo!!!! For the rest of their existence
Haha! Well, if they die, little girls will be sad that butterflies will die, but, since a species has fallen, a new one will probably rise, a new animal, maybe a giant lizard with wings that shots out fire of his mouth? Dragon? Anyone? Well, if that doesn't happen then we will have flying Butter bars through the skies, i can imagine the news saying ''Today, you can see flying Butter at 3:00PM, they are migrating to what used to be north, now south, please do not bite any.'' :D
ZDavePlays what will mainly happen is for one generation of butterflies they wont know where they are but once more are born they are born into the new magnetic field so they will be fine
ZDavePlays during magnetic pole shift the side facing the earth would be fried by thousands of degrees c. and the line of the rising Sun on our lovely planet would be our last morning unless your were buried a mile underground with food water for a few decades or more
You forgot to address what will happen to the migration patterns of animals that depend on magnitism for navigation. Care to explain?
I wonder too. I suppose some species won't care. They'll ignore the magnetic clues in favor of coastlines, wind, sun, smells, whatever. Some species will be partially messed up, maybe lose some % of their magnetically stubborn population, but will survive overall. Almost every species of creature on our planet now, was around thousands of years ago, and must have gone through a magnetic reversal or two or three.
it will flip slowly but surely
Half the comments are about the name change, the other half are actual comments
Has anyone heard of variation ?....we re-calibrate magnetic north all the time.....so if it flipped we just re-calibrate...nothing will happen physically.....these fellas just love the sound of their own voices
okay, I still don't get it. How do rocks and clay show anything about the Earth's magnetism
I know right? wtf? Rocks solidify from molten magma, they trap the iron orientation which generates a magnetic field when a lot of iron cools with that orientation, that to me is clear. Pottery is talked about as a probable recorder of magnetic field intensity, not orientation. I guess the next question is: why hasn´t the pole shifted in the last 400,000 years when it should have? or: why now?
Because rocks contain iron bearing minerals, things that react to a magnetic field. Here's a tip, use your computer for something other than TH-cam and porn. I never get why people ask something that they themselves can simply look up.
Well Said!
So i guess it flip already for some reason i see Seeker instead of Dnews
It's been flipping for ever constant cataclysms every 6,000 years give or take. We're fucked.
You've addressed me yet again! Not only during the pole switch will magnetic north become south, but civilization as we know it will cease to exist. Such a pole shift will give rise to tsunamis, seismic events and electromagnetic phenomena of a like we've not seen since the destruction of the previous civilization.
how should i imagine the magnetic pole flip. is going to flip instantly or ist going to flip in a certain period of time by moving slowly from north to south an vice versa?
They call me the seeker.. I've been searching low and highh
So if it weren't for science the magnetic poles would switch and no one would notice or care... I love science!
The Fax Fox that isn't the case at all. Not only would people notice, but they would be saying bye bye to all of civilization. It's not just a simple switch upside down. We're talking total catastrophy.
Chandler Ehh, the most (and that's pushing it) is a power outage for a few days, and satilites needing recaibration.
The best outcome is that birds are confused, because it takes decades to fully flip, meaning it's unlikely going to be a " everything turns off at once" deal.
Chandler are you serious? The magnetic shift doesn’t happen suddenly it’s happening already and the magnetic north is actually moving every year and we are calibrating everything according to that
I am a pilot we use the magnetic compass a lot , the charts that we use are updated to keep us aware of the magnetic variation, so no magnetic shift will not have any catastrophic effect on us because it’s not sudden it’s very slow and constant movement
atef ali the poles could actually flip at any moment in ant period of time scientist studied the body of a mamoth some time ago and discovered that the sediment in his stomach was pretty much fresh and not digested... this suggests that the poles flipped extremely fast some say within 30 mins
atef ali and it will be bad the oceans will slosh and many coast will be flooded look into my guy there are tons of vids on this site alone talking about it, im surprised seeker didn't make it seem more urgent
great video and narrating.
'd be cool to see the more detailed magnetic picture and how it is done. Thanks!
WHAT IF OUR OPPOSITE DIMENSION FLIPS TOO?
as in, if time as we know it is going "forward" and our mirror universe's time is going "backward" (but time is relative, so the "backward" feels normal) then when the magnetic field flips, im sure that the mirror-verse's field will also flip!
now.... COULD THE MAGNETIC FIELD HAVE ANY EFFECT ON TIME?!
Mind blown
Cant tell if you're being sarcastic or not🤔
*IMPLODES*
Soooo... Earth. We know you are bi-polar, swing both ways, & have had a pretty wild past. We're here for ya man. One thing tho...we're wondering if the Moon is your illegitimate child.
Cool, but what can we do about it weakening? Is there anyway to strengthen it?
Actually the magnetic north is close to the geographic south, our magnetic instruments just have the markers flipped to make it less confusing.
I'm so early, there is no comments. WOW
Hi
Hi
Hi
Hi
Hi
hello!
So, how fast will it happen?
Will it be instant change or over a couple of days or weeks....?
You know how you missed it. The Dynamo Coriolis effect. When the magnetic fields flip it's a planet's rotation. For 7 to 10 minutes but while they orientate themselves and then the planet spins in the other direction. That's where your evidence is off with the magnetic dust particles. Lining up in your timeline check it
Btw.. Do you know that recent findings by archaeologists showed that Indus valley Civilization (Indian) was the oldest civilization among Mesopotamia, Egypt, and Sumerians. Almost 9000 BC.
This changes everything.. of how we perceive events in history.
What if the dates on the pottery aren't actually correct...
Spyro Tek carbon dated
Yeah, but I'm referring to the part in the video where they say that they know the dates because the date is on the pottery.
Spyro Tek - Which has been carbon dated so they know the dates on the pottery is accurate... It isn't hard to understand.
ALGERIA48 Bechikh - You're* Learn English before trying to look 'clever' on the internet. "Your" means something completely different.
They aren't using literal dates on the pottery, they are dating the pottery based on known stamp technology available and who the royal stamps belong to. The window it narrows it down to is huge on the scale of a human lifetime, 15-20 years, but compared to being accurate to + or - 1000-2000 years being accurate to + or - 15-20 years is pretty significant.
I'd like to know how you think the earths core is going to stop and then start turning the other direction. Magnets do not flip. They get weaker and weaker until they die.
New this fall on HGTV, "Flip That Pole"

Suvi-Tuuli Allan no thanks I'll pass
I just find it hard to believe that a magnetic pole switch won't affect our bodies- since there's iron in our bodies etc. - or maybe I'm just overthinking, or perhaps underthinking! :p
Great video!!
I don't mind name change it's change of comedy tone with lighthearted music to serious and eery with mysterious music.I don't like it at all
Chobruh I think you're the only one who enjoys the cheery music and horrible jokes
Joel Verrier the jokes were cancer it was seeing them try to be funny and the light hearted tone of science that I found different from all the serious ones to,and maybe I am but honestly I think I'm not the only one who appreciated the non serious tone
Dude...iron your shirt
Mark McArthy Ha! I thought the same thing and wanted to see if there was anyone else in the comments. Great idea!
A magnetic feild reversal is a extinction event . In fact every single time there is a reversal thier is a extinction event directly afterwards. And it can disappear completely or turn off for a couple hundred years depending on what kind of reversal it is
I thought the magnetic poles flipping could possibly cause a wipe out of a lot of humans
Dude
Cut the two sides of your hair
don't listen to him
Morgan B to
Sort of looks like a north Korean style hair cut lol Kim jong un.
I like it :D
TH-cam at it again. Subbing me to channels I didn't sub to. Unsubbed
Todd Lingnau it's DNews
Todd Lingnau Lol this is DNews. They just changed names. Don't blame TH-cam 😂
Cool video!
I want to see you do a class on the Dynamo Coriolis effect
This is what Islam said about it and that is all true!..(a thousand years ago). To all the people who read this...Pleasee pleaseee and pleasee Remember this MASSAGE from me...->Before the sun rise in WEST , the earth will be at night time about 2/3 day without the sun light. And when the sun rise in West, every single one human that exist in this planet on that time will convert to Islam....because what? Because they know what I'm saying right NOW and the fact that Islam is not lying is totally TRUE. :")
The Earth is flat
Half left Bob.....Even so, how does that affect the magnetic field?
hes trolling, everyone knows that the earth isnt flat xd
Husq Designs Only people trolling here is NASA
He's not actually trolling, he believes the earth is flat 😂 but as his name states he's not right, he's only half left
Ger - If you don't believe Earth is flat you're a dipshit
No "sudden changes" from North to South . A reversal is a complex and chaotic process that takes at least 100-200 years on the short end.
the name change confused me at first since i'm also subscribed to Seeker Daily. cool video though.
very informative. .thanks.
Excellent as always
Lol. For the past week or so I've been so weirded out by why I kept seeing these seeker videos in my feed. Today I finally smartened up to watch that Pluto video and figured out wtf was going on XD Good luck with your new branding, and everything guys. DNews made a fan out of me, and now that I know that your still basically DNews, I'm not going anywhere.
Is it more correct to say that pole will flip, or that the poles are flipping? I recall reading somewhere that when they do flip, the process might take many decades of even centuries in which case we might already be witnessing the beginning of it.
Oi Skeeker! So when do we expect to flip the magnetic poles? This was a nice intro but nothing new for me and a lot of other peeps.
any predicitions on when it will flip?
Hey man, it takes hundreds if not thousands of years for the field to flip.
We are in the middle of the slow process right now. It's not a big deal at all.
0:57 "It's not like it would turn off - *BUFFERING* and turn back on."
The video actually buffered for me RIGHT as he said "off", super weird.
How long does the flip actually take? Is it gradual or as the poles weaken and begin to move is there a breaking point where they quickly flip? Or neither?
It will happen over about 2 years. Then a quick flip will happen
What is the song in the background!? I love it!!!!
When the poles flip the field weakens and weather gets crazy, life does off. Sooo, close enough to turning off/on.
Are there any theories on whether the flip will happen in decades, centuries, or meliueua?
Wait....SEEKER IS DNEWS!!! That makes more sense why this channel was one of my subscriptions that I never knew. lol.
Serious question: If like poles resist and opposite poles attract, when one magnetizes the tip of a needle to make a compass, is s/he making it's tip negative (south)?
Nicely done.
Im confused, do you have the research papers on the core sampling they did in the mid-atlantic ridge? The reasons I am confused is that you spoke about the magnetic field having been weakened by 10% or so the last couple of decades (or was it centuries?). Either way, I don't see how that fits with the timescale you presented for the flip.
