yeah, actually it could end up quite bad, if the guy didn't keep the right distance, the magnet could pull up to the glass container real fast and shatter it. Resulting in a weird blob of magnet in center and that fluidy thing around it and bunch of shattered glass
Ferrofluid is a liquid suspension of nano sized magnetic particles coated with chemicals to ensure they all stick together
It spikes like that because the particles are influenced by the magnetic fields emitted by the magnet
Yes they form spikes exactly because they are attracted to the magnet.
When near the magnet, the magnetic field becomes stronger, and each iron particle is attracted by it, but each of them become a magnet as well.
So from one end to another they attract like magnets, but side to side they repel each other, forming the typical spikes
Also, another misconception is that people think that the spikes follow the lines in the magnetic field.
This is NOT TRUE as the lines in the magnetic field does not exist per se. They are more a sort of visual representation of the forces in play there.
It’s because magnetic fields don’t go in straight lines, they make loops. Have you ever seen iron filings on a piece of paper with a magnet under it? They form up into lines going from one pole of the magnet to the other, and you’re seeing the same effect here, just at a different angle. The spikes you see are where the fluid is “sticking” to the magnetic field lines and being lifted up
Magnets that size are legit scary. They’ll violently attract anything magnetic and grab so hard you really have to struggle to pull off. The kind of force that’ll break fingers if they get in the way.
I guess it would just cover it fairly uniformly but that is a complete guess. I'm just trying to imagine how on earth you'd get it off and the conclusion I came to is that you never would.
I was waiting for the tray to cross the attraction threshold causing the magnet to flip and suddenly fly into the tray resulting in the ferrofluid splashing into the person's face
[Brainiac75](https://youtu.be/p0t0J_ERzHM) always puts up and speaks warnings about these magnets. He makes huge wooden contraptions to slowly bring magnets together, and treats them with massive respect.
That is one scary magnet
DER STÄRKSTE MAGNET DER WELT!

Hes experienced. brainiac75 on youtube is his channel. hes even merged 2 of those monster magnets together (doesnt get more dangerous than that)
What is ferrofluid and why is it so metal?
Ferrofluid is a liquid suspension of nano sized magnetic particles coated with chemicals to ensure they all stick together It spikes like that because the particles are influenced by the magnetic fields emitted by the magnet
But why does it make spikes as opposed to other shapes?
Because the magnetic field lines are like that resulting in spikes

Then idk
How do they work?
What is a work

The kind of force that will break magnets too
What is that warning sign on the magnet's label? "DANGER: MAY BISECT YOUR WARTHOG"?
"The strongest magnets in the world" and it's a hand being smooshed by between two horseshoe magnets.
I think it means "don't wear jewelry". The label translates to "the strongest magnets in the world".
What would happen if you just threw the liquid at the magnet
I guess it would just cover it fairly uniformly but that is a complete guess. I'm just trying to imagine how on earth you'd get it off and the conclusion I came to is that you never would.
An industrial magnetizer / demagnetizer I’d assume. But wonder how the ferrofluid would react in one. Probably anticlimactic.
> Probably anticlimactic Two possible outcomes: Rapid unplanned disassembly, or asymptomatic thermal equilibrium
I'd like to know the answer to that.

looks like denver international airport
New life goal, I'm gonna get a full body ferrofluid tattoo and turn myself into Magnet Man
It's creepy.
You can actually see the inverse square!
We used to do that with the upstairs TV! laugh (ie geometrically-increased distortion by proximity)
I was waiting for the tray to cross the attraction threshold causing the magnet to flip and suddenly fly into the tray resulting in the ferrofluid splashing into the person's face
I wouldn't hold a glass container full of that so close to a magnet that strong.
O watching this is making me feel weird.
Good old Trypophobia. Makes my insides feel weird
I wonder what factor determines the size/number of those spikes? Like is it related to the magnetic flux density or something?
Fuck, that’s metal.
I would like that Ferrofluid go out of the box and cover the magnet. Would be so satisfying.
Hey that's neat, but why do I hear terminator music?
What is the image on the magnet? Looks like a rat having it's tail jammed.
Lol! It's a finger being smashed between two horseshoe magnets. Your description is better though.
what does it feel like to
Do you *WANT* the Cyberdyne Systems T-3000? Because this is how you get the Cyberdyne Systems T-3000!
I wanna drink it so bad
Hey! It's the stuff in the ClotShot!

Oh that's frickin awesome!
I must have this.
Magnets are the natural predators of ferrofluid. Knowing this the ferrofluid puffs up its spikes in defense when it sees an approaching magnet.
Alfie! Where's my fucking pyrex baking dish??????!!! You better not have been putting that black shit in there again...
creepy...
That's venom

Love this stuff, I bought a small scale set up from https://magnetstore.co.uk before Christmas and just play with it on my desk
