Dynamic sculpture with ferrofluid

This stuff has military potential, use magnets to have it cling to you on a vest or vehicle part, then rig it to apply a powerful magnetic charge when it detects impact then bam, you have a rock solid, jet black spiky shape saving your ass, the Russians and US are already playing with it in this way

I call blatant lie. Ferrofluid is just magnetite suspended in oil. I highly doubt it gets hard enough to stop a bullet, magnetite is pretty brittle stuff.

Also, let's say what you say is true, and there is a military vest with ferrofluid inside. All the enemy has to do is make a magnetic field and your soldier has very limited mobility, and is likely to be killed. This is especially possible in urban warfare.

correct.. it will feel like "a springy fluid" if you touch while its magnetized... hope that makes sense

Never before have I witnessed sorcery of such a high caliber

how does this works ?!?!

Does something happens if you touch it or it just keep going like that?

Actually, iron oxide is FeO2, which is rust. And the word you're looking for is ferrite, not ferro.

Also, the ferrofluid never changes state, and it's magnetic FLUX, not pulse.

even though it's meta and it looks sharp using it like that would really be the equivalent of attacking someone with swords made of jello.

you can buy ferrofluid online. its moderately priced, comes with just the fluid itself and soemtimes a magnet. you can experiement with it if you have an electromagnet.

not realy
