Electromagnetism is a branch of physics that studies the interactions between electric and magnetic fields. What are your thoughts on this force of nature?

[HappyGrower]

It's amazing how magical the world could be without actual magic.

[a.s.m.islamulhoquelaskar]

Wow, if only my physics teacher would have made me understand like that, I could have been wandering something different in life!

[newcreationinchrist]

Cool. Our world is truly amazing. At least it is to me.

So, that's what it means when people say the more you know, the more you know you don't know. This video just left me with so many more questions.

I didn't know the word geodynamo yet, so I'm gonna do some more research on geodynamo

[AriaHarmony]

This is amazing! Very clearly explained. Thank you <3 It's strange and magical how seemingly unrelated things all fall under the electromagnetic spectrum.

[voodoodiecast]

But flat earthers still couldn't understand.

[AminulIslam-vcbx]

Electromagnetism...the word is very amazing.😍😍😍

The north magnetic pole of the Earth's magnetic field is currently in the Antarctic and the south magnetic pole is in the Canadian Arctic and moving towards Russia. The pole of a bar magnet that points North is called the north pole of the magnet. Since opposite poles attract, the pole to which it is attracted must be a south magnetic pole. By convention, the direction of magnetic field lines is from north to south; this is the direction that a magnetic compass points. So the field lines shown in this video should be towards the geographic north (approximately) and not towards the south.

The electromagnetic field is literally the force. It flows through everything, and we can manipulate objects with it. However, the force in Star Wars appears to be more strong since you can literally pick people up with it, meanwhile our electromagnetic field can only pick up metal things if we make it strong enough.

our brains create electromagnetic frequencies...think about it

[Rainzlet]

It's truly beautiful how the language of life is holding us together. Really if we think about it, we truly are connected together.

[narayanisiware]

We are living in a magical world, and still we want to see magic?

[gvamshikrishna]

If only there were more such videos while I was growing up, I would have become an Astronaut by now.

[vinhluu]

I need to find out what is magnetism and how to apply it in our life now, Thanks National Geographic for creating this

[darkorse]

Actually, we're coming to understand that the gravitational force falls in line with electromagnetism, and that electromagnetism is the strongest force of nature. Not only does the Earth's core create the north and south electromagnetic forces, the electromagnetic force also causes the Earth to rotate.

The universe is breath taking! The dance between Electricity and magnetic fields is amazing. I enjoyed this video. Try to incorporate it into your beliefs. There is no way the universe is here by "Accident"

national geographic is the best !! i can find everything here !!!
