ERROR AT 2:41 ; The earths poles do NOT attain positive and negative "charges". That's describing electrostatics. When talking about the magnetic field, one refers to a "B" field- NOT something that is +/- . There are no magnetic monopoles. There is only a direction to the magnetic flux. (INTO the north magnetic pole and OUT the south magnetic pole). I was liking this video for class review until I saw that section.
Thanks
Lies. Molten metal doesn't hold a magnetic charge. Neither can it create one. Prove me wrong.

thank you so much this helped so much😄😀

Very interesting most take notes
It's soo amazing!
The video missed to point out that this dynamo inside the Earth is an unconfirmed hypothesis. Nobody has been 'thousands of miles below the Earth's surface' to verify what's there.
You can connect to the earth's frequency like wifi charging a phone and generate an infinite form of renewable energy
Tesla did this
And yet someone still don't believe in God
it's as interesting as nixon moon phone and 9/11 plane collision. "2 planes" "3 buildings"
National geographic, i have a question, can earth's magnetic field attract something large that is ferromagnetic?
Thank u national geographic for giving a brief explanation from your hard research.
Respect.
Now the question. What's the purpose of life if consuming more electricity will strengthen electromagnetic field of any planet with metallic core?
The antiverse collapsed and our universe began..
A big endless bounce..between our universe and the antiverse..
The antiverse is as amazing and wonderful as our universe but exactly the opposite..in the antiverse energy not matter is alive..and aware…
In the antiverse our sun is a darklight consuming star that eats up energy there, to shine light here in our universes .as the antiverse shrinks
Ours will grow..
Somehow as our universe grows these time allowing particles aka beauty quarks are finding it harder and harder to find their way back into and stay in the antiverse..
So our universe will collapse and the antiverse will once again begin to expand..
Time allowing particles or waves can be manipulated with strong enough magnetic fields we must develop quantum magnetic engines to travel to far away places within our universe…
thanks for the lesson
I would have been a physics major had my younger self understood these lessons much more clearly years ago.
I'd always wish school was these videos:)
🙌
Hot iron loses it's magnetism.
Just think! Most of Earth will be getting FREE power soon. Thank you Tesla, and Trump who "inherited" (spoils of war) the Patent and is releasing it to the world!
why earth magnet can repels sunbursts? although magnet can attract anything.
If I eat magnet can I become invincible ?
All theory
This is amazing! Very clearly explained. Thank you <3 It's strange and magical how seemingly unrelated things all fall under the electromagnetic spectrum.
