What Do Magnetic Fields Actually Do? | SciShow Compilation

So what exactly do magnetic fields actually do? What would happen if they went away? Turns out, it could be catastrophic! SciShow will explain it all in this fun new episode hosted by Michael Aranda!

This could've been very confusing, so thanks for explaining this in a way that even I can understand! I'm absolutely horrendous & have a learning disability in maths, so I always appreciate the way the hosts explain confusing and/or complicated news. 😊👍

Someone please make a timelapse morph of Michael's hair over the years

[chuckesthedoughboy]

Running a CAT mag crane everyday made coming across this video even more exciting. It’s so cool to learn new things about something you use all the time

[Pandaemoni]

I would have assumed that the Earth's molten core is turbulent and so changes in the magnetic field might just be chaotic (in the mathematical sense) and not require an external "cause" each time. Like hoiw with a double pendulum (also a potentially chaotic system) sometimes the pendulum will flip over the top of its pivot point, 360-degrees. You can't easily predict how long that will take in advance, and most of the time it won't, but if the pendulum has enough kinetic energy it is inevitable.

Regarding a fox's attack. Since it always appears to align itself to a specific magnetic direction, could it also possibly be setting itself up in a blind spot of its prey?

[BooBaddyBig]

So to sum up, 'Fortunately the Earth's magnetic field is not strong enough to pull our atoms apart.'

Katelynn sp? Clip was awesome. Learned a lot about planetary magnetic fields thank you

[jasonwebb]

Along time ago I was told that the photo of Earth was upside down. Meaning that Australia is closest to the top of the world than Canada. But that's what really gets me though. Depending on which way you are turned in space, is what makes the difference. Maybe the Milkyway is upside down compared to most of the galaxies out there. Lol

10:05 I think the way these animals experience magnetoreception is probably more subtle and just sort of baked-in feeling; like all of our senses. It’s probably just a subtle, biological “feeling” when they’re pointed in the right direction.

[joshuachristofferson]

10:24 more importantly, how has Organic Life that depends upon the Magnetic Field adapted when it has flipped in our Past?

[mnichols]

My dog does the same thing the foxes do with the pouncing. He's real good at getting the moles and voles in my yard

[crazychild]

She was soo informative Holy mother of gawd

[rpbajb]

A new theory hypothesizes that the moon causes tides in the earths mantel generating the circulation necessary for field creation.

[EyesOfByes]

5:24 *There are two kinds of people; Those who can extrapolate from sufficient data*

[desertdragon]

A little brain food. Good stuff. Bravo!

[davytyler]

"We like an unproblematic magnetic field."

That's a good quote right there.

[nenume]

Michael graciously owns all the hairtyles of rock subgenres. Mohawk next?🤣
Also, wouldn't artificial huge magnets work as a replacer for, at least the fauna?

[twocvbloke]

You could say, Earth has a 'magnetic personality'... :P

If we're discussing Geomagnetism, why wasn't the increase of the geomagnetic polar drift addressed at all? Y'all even posted a video about it, May 7th 2021, extrapolating it to climate change, even when most of your sources even said more research is needed for a cause to be more accurately attributed. I would love for y'all to do more research into it and discuss your findings, its a research project in which I've found myself begging for more data and papers!

[jokerace]

That's actually quite interesting, Kaitlyn. Could those bubbles of atmosphere be harvested for fuel in a large orbit of Jupiter with the right characteristics to intercept them? Elon isn't wrong about identifying easy to aquire sources of fuel in order to explore the outer planets and moons. A fuel stop on the way in or out of the Jovian System would be a helpful thing.
