Earth's Dynamo Explained

[@giiashin]

your enthusiasm and detail made the video far more interesting and helpful to watch! thank you so much for your video:)

[@tastethejace]

The guy is explaining mind-blowing science and the audience is like "mehhhh...."

[@mi5iu491]

They're prolly taking this class to fill a credit

"Hi, I'm Saul Goodman. Did you know you have the Earth's magnetic field protecting you from solar radiation? Science says you do."

[@zikermu]

You have excellent methods to quickly explain complex phenomena .Bravo.

[@AdityaThakur-jb6sx]

you are a really good teacher!! we need more teachers that have such high interest towards teaching the subject... thank you sir!!

[@stephenwithaph1566]

Found this video through ChatGPT, what an excellent video!

[@himanshuojha8466]

Stupendous teaching sir

[@MrMoose123]

Thank you! That demo was so much fun. I wish I had a camera on the students all plugging their ears from the previous universe ballon demo!

[@niueanlaho]

wow that is so cool........but what cause the liquid in the core to move?and how is the core so hot and what keeps it staying hot.....wouldn't it so cool to send a probe that can withstand the temps down there to actually see this all in motion.....

[@Wutheheooooo]

Liquid iron and metals move because the moon gravity pulling it, and yes the earth's core is slowly cooling.

[@Shubhmegh]

Just amazing, how well you explain this sir.

[@d-knowledgehub8341]

Hats off Sir Respect from🇮🇳

[@ErnestoFavor76]

Great teaching! Enjoyed it a lot.....👍🏼

[@ernestb.2377]

Question: if solar winds are detrimental for the earths atmosphere and as the charged particles are guided towards the earths north and south pole what is the effect on the earth atmosphere at those 2 areas?

[@MrMoose123]

Those areas have an incoming flow down into the poles of the Earth. If there was no magnetic field the atmosphere would be wiped off into space.

[@ernestb.2377]

@MrMoose123 thank you, I know that,

[@omkar8692]

such a nice explanation...loved it

[@borisbeloudus2691]

I was looking for a KZbin video involving a rotating molten sodium sphere and the effects of radiation on the magnetic poles

[@OxbirdR]

Beautiful !!

[@therombaro]

Does anyone have that youtube link from the lecture? I want to learn more about this.

[@omkar8692]

kzbin.info/www/bejne/hGbYpYSuqdKUaLc idk this if this is the lecture link but it pretty much explains it.

[@johnhopkins6260]

Does the rotational direction of the earth/core(s) determine which pole is North/South?

[@MrMoose123]

Here’s a great description on that www.nationalgeographic.com/science/article/magnetic-north-update-navigation-maps

[@kameshchaudhary7946]

Great explanation

[@AlexRapala]

this is great, extremely helpful, thank you so much

[@Avi-fs4rw]

why is the category comedy?????

[@johnreder8167]

thank you and you're amazing teacher!

[@pratimasingh489]

Well explained

Cool dr marten.smart like me hehe.handsome.good guy from usa.i love usa.kerennnn

@@MrMoose123 name of the video in question?

[@garrettingle6728]

Will we see a lot of aura’s when earth goes through a polar inversion?

[@MrMoose123]

Great question, it’ll depend on the strength of the suns corona mass ejections and strength of our magnetic fields to direct energy to the poles.

[@guidedmeditation9197]

Great.. Thanks..

fucking amazing.

you're an elite tier teacher

I hope usgs and elon musk understand this.i tried so hard to make world understand that earthquake time.periode really can predict now till minute.amazing.by watching this movie maybe they will listen.

that didn't really explain anything... move two chunks of iron past each-other nothing happens..

[@karhukivi]

It happen inside most electrical generators, they have "field coils" and generate a magnetic field in the same was as is explained here, which is why he has an image of such a generator!

[@vandanagupta-vs8dw]

Anybody explain in Hinglish I can't understand

[@Awakeintheaether]

Thats a lot of presuppositions....we've only ever dug down 7.8 miles but youre going to make positive claims about whats down thousands of miles? And with mars, we see a luminary in the sky...youre showing cgi/animations of "mars" and making up all these "facts" about its core😂 when you nor anyone else has ever been there...

[@karhukivi]

When the medics do an MRI scan they can see your internal structure and organs without "digging" into you. In your case they probably couldn't locate grey matter however.

[@Awakeintheaether]

@@karhukivi False equivalence logical fallacy^^ we've still dissected the human body to see what its like inside. We haven't for the earth. Also, the human body isnt thousands of miles deep....

[@karhukivi]

@@Awakeintheaether You never heard of seismic tomography using earthquakes? How shear waves don't pass through the liquid Core, while compressional ones do? Never heard of magneto-tellurics? Never heard of angular momentum, or the density of the Earth? So what do you think the interior of the Earth is made of?

[@Awakeintheaether]

@@karhukivi Thats like you saying the bible is bullshit and me replying with, "oh yea??! Ever hear of the 10 commandments? Noah's ark?? Jesus Christ?? All the expert priests who went to seminary school agree with it."

[@karhukivi]

@@Awakeintheaether Well, what do YOU think is inside the earth?

[@dcummings7253]

Cough Cough Nickel Iron core you say. That is stainless steel. Good stainless steel is non-magnetic. Good theory though. Keep at it you'll come to the truth one day. Maybe.

[@MrMoose123]

Cough cough, where did you hear about chromium in this lecture??? Stainless steel is reliant on chromium oxide to shield the surface from further ‘rusting’ and many alloys of stainless ARE magnetic. I think as a typical couch potato critic in your haste doesn’t know anything about geophysics, if you did you’d realize that all this is theoretical since it is ALL estimates from sound waves velocities. Crawl back under your pedantic rock and go troll someone else!

[@karhukivi]

Many meteorites are nickel-iron alloy and are strongly magnetic. They are common (although hard to find) and they fit all the seismic, density and electrical conductivity parameters that we know exist in the core from geophysical studies. What do you think is in the interior of the earth? gold? chocolate?

[@dcummings7253]

@@karhukivi LOL heat them to molten then check your magnetism. A cold meteorite may be magnetic. Not a glowing hot one. As for the interior nothing can be proven. The deepest hole ever drilled is less the 8 miles.

[@karhukivi]

@@dcummings7253 Very true, but the Earth's magnetic field does not come from a ferromagnetic material, it is produced by a circulating conductive liquid and the self-exciting dynamo effect, which incidentally is how most electric generators work. The worldwide network of seismic stations monitor earthquakes (and illegal underground nuclear tests) and these prove that the interior of the earth has a liquid core as shear waves don't pass through non-rigid liquids. We know the mass of the earth from gravity data and the volume from the dimensions, so we know the average density which is a lot higher than even mantle rocks, so we know the Core is a metallic liquid. What do you think it could be - mercury? gold? Irn-nickel ticks all the boxes and is common in the asteroid belt, so the most likely candidate. That is how science works, using evidence, and not based on "beliefs" which is what religions do.

[@dcummings7253]

@@karhukivi Well your faith in your science. If no different then my faith in the Creation and what I believe was all explained in Genesis. And to me is not explained away with your faulty science. Psalm 104:5 He established the earth upon its foundations, So that it will not totter forever and ever. Genesis 1:7-9 And God made the firmament, and divided the waters which were under the firmament from the waters which were above the firmament: and it was so. So no there is no center the Earth is a level plain.
