Alternatively, what would happen if the loss of magnetism instead happened gradually over a period of time?

Every single electrical item on the planet stops working, because every generator, turbine, and motor immediately stops running.

Car batteries never charge, starter motors won't turn, and any hall effect sensors cease to operate.

Kitchen floors would be covered with souvenirs and notes.

Society would collapse

[–] zaugofficial@lemmings.world 30 points 1 day ago (1 children)

I'm no expert, but I feel like magnets losing their magnetism would also cause electricity to stop working.

[–] Twanquility@feddit.dk 10 points 1 day ago* (last edited 1 day ago)

Most electricity is being created with the use of magnets i motors/generators. No more electricity then.

Asides from batteries and solar.

[–] Appoxo@lemmy.dbzer0.com 28 points 1 day ago (2 children)

The earth is a giant magnet.
You'd be burned to a crisp by solar winds ;)

No, you wouldn't. You'd start getting cancer.

Also, the atmosphere would start getting worn away. Most people would die of cancer before it'd get bad enough to asphyxiate everyone though

How didnt I think of that... facepalm ;D

[–] GreenKnight23@lemmy.world 8 points 1 day ago

generally speaking, mass chaos and hysteria and then nothingness.

if we exclude the possibility of "magic" doing it, and instead focus on the realistic causes of a loss of magnetism the chances for just magnets to be directly impacted are low.

that is, the strength of phenomena that would be required for all magnets in the world to cease functioning it would also likely cause the magnetic cohesion of molecules and atoms to break. this breakdown at the atomic and subatomic level would cause a chain reaction where we would both cease to exist and explode with enough energy to destroy the universe.

if any atoms of you survived at all, they would be flung to the outer reaches of the universe in seconds only for the entirety of the universe to be sucked into the void such an explosion caused. it would probably be something akin to a big bang.

[–] ThePyroPython@lemmy.world 22 points 1 day ago (2 children)

Rather than listing all of the ways modern life and society would collapse it'd be easier to just say this:

Your ability to understand the world would in an instant be limited to the people that immediately surround you and you'd better quickly think of a way to find a clean water source, some land, grab an "Agriculture for Dummies" book, and some form of weapon to defend your new homestead with your new tribe.

[–] frezik@lemmy.blahaj.zone 5 points 1 day ago* (last edited 1 day ago) (1 children)

Nah, don't worry about that shit. The earth just lost its radiation shield.

[–] ThePyroPython@lemmy.world 5 points 1 day ago

Well is this about permanent magnets loosing their functionality or the whole concept of magnetism just vanishing?

One puts us back to a steampunk technological ceiling the other means the universe pops out of existence; electricity, magnetism, and light are closely linked so removing one is likely to just break reality.

[–] nutsack@lemmy.dbzer0.com 2 points 1 day ago

bro stop im gonna cum

[–] charonn0@startrek.website 82 points 2 days ago (1 children)

Depending on what counts as a "magnet", the loss of magnetism could destroy the universe.

[–] aeronmelon@lemmy.world 37 points 2 days ago* (last edited 2 days ago) (1 children)

Maybe the exercise should be limited to all ferrous metals just became inert.

[–] halcyoncmdr@lemmy.world 31 points 2 days ago (2 children)

Welp, bye bye to the shield against the Sun's deadly laser. Although I guess that also means bye bye to the laser too? Hmm.

[–] aeronmelon@lemmy.world 9 points 1 day ago

Can’t get sunburnt if there’s no sun.

The Earth's magnetic field is gone and we all die.

[–] PumpkinEscobar@lemmy.world 15 points 2 days ago

Finally, some good news!

[–] quediuspayu@lemmy.dbzer0.com 10 points 1 day ago* (last edited 1 day ago)

On the bright side we could stop wondering how do they work.

[–] Generica@lemmy.world 2 points 1 day ago* (last edited 1 day ago)

People couldn't use their MagSafe iPhone accessories and society would crumble within days (You can't tell me I don't know what Vietnam was like!!)

[–] PeriodicallyPedantic@lemmy.ca 36 points 2 days ago* (last edited 2 days ago)

If you mean a complete absence of the electromagnetic force, then chemistry and physics are going to get very disastrous for us very quickly

[–] Blumpkinhead@lemmy.world 6 points 1 day ago

All the shit would fall off of my fridge.

[–] sanguinepar@lemmy.world 47 points 2 days ago (2 children)

Are we including electromagnets? If so, an awful lot of motors would suddenly just not work anymore.

[–] Humanius@lemmy.world 10 points 1 day ago

Electricity generation would suddenly also get a lot harder. Without dynamos I think the only real option becomes solar panels.

[–] notsure@fedia.io 16 points 2 days ago

...magnets is quite general, but i believe it counts, and yeah, fucking everything stops...

my hard drives...

[–] aeronmelon@lemmy.world 38 points 2 days ago (2 children)

We just lost all data still being stored on magnetic drives and mediums.

Compasses just became useless.

A lot of medical and scientific equipment suddenly stopped working.

The MagSafe charger on my computer just fell off.

[–] blackbrook@mander.xyz 1 points 15 hours ago

Not gyrocompasses that things like planes and missiles uses, just the kind low tech hikers use.

Exactly. This is clearly the biggest problem. Who cares if every atom in the entire universe gets shredded in a new big bang when the screen of my iPad might get scratched next time I toss it in my bag.

[–] owenfromcanada@lemmy.ca 32 points 2 days ago

Everything would come to a halt, quite literally. Pretty much everything that moves using electricity uses magnets.

The rest depends on what you mean by magnets. All magnetized materials? Now all computers and internet are gone. The ability to create magnetic fields using electricity? All manufacturing equipment becomes scrap metal. No magnetism anywhere with anything? The universe implodes.

[–] venusaur@lemmy.world 17 points 2 days ago

A lot of kids’ art on the ground

[–] Tedesche@lemmy.world 19 points 2 days ago

You’re talking about a change in one of the fundamental forces that govern the universe. Things would start falling apart at the atomic level, including in your brain. I don’t know that you would remain conscious for long enough to observe anything. I don’t think anyone could tell you what would happen because we’d literally have to re-calculate physics without electromagnetism. I don’t even know that that’s within the scope of human imagination.

[–] Treczoks@lemmy.world 13 points 1 day ago

You would hard pressed to learn about the details without electricity and communication networks.

[–] Blue_Morpho@lemmy.world 19 points 2 days ago

Electricity and magnetism are the exact same thing. A non moving charge creates an observed static electric field. A moving charge creates an observed magnetic field. So if you were moving next to the charge as it went down a wire, you would see no charge moving. No charge moving means no magnetic field.

They only look different because things get distorted moving at near light speed relative to you. It would be like if we gave two different names to a police siren based on whether you were listening standing next to it or listening as it zoomed past you.

[–] sanguinepar@lemmy.world 11 points 1 day ago (1 children)

A fairly disastrous set of outcomes described in the comments so far.

Thank goodness though, that you didn't ask about there being no springs.

[–] sawdustprophet@midwest.social 3 points 1 day ago* (last edited 1 day ago) (1 children)

Let's not even talk about zinc.

Ha ha, wow, someone at the Simpsons is an MST3K fan, I think.

All electricity generation would stop

[–] Bwaz@lemmy.world 2 points 1 day ago

According to Trump, a rainstorm would cause that to happen. But wouldn't put out the fire that is Portland.

[–] Rhaedas@fedia.io 11 points 2 days ago

Magnetism is "just" the ability of some elements to line up their fields so that the effects are felt beyond their electron shells. It's much more complex than that, but magnetism is in all matter, just some more than others. For it to stop at any rate would be like changing a constant of the universe. I would imagine very quickly things would be very different and we wouldn't be around to witness it.

[–] Kolanaki@pawb.social 10 points 2 days ago* (last edited 2 days ago) (1 children)

We wouldn't be on the internet talking about it, that's for sure. Electricity wouldn't exist anymore outside of lightning.

Does that include the magnetic fields of Earth and the Sun? There'd be significant knock-on effects from that potentially causing severe long-term consequences for life.

[–] ThisSeriesIsFalse@lemmy.ca 5 points 2 days ago

Magneto would be very, very sad.
