What is magnetic liquid?

Answer 1

Yes, it can because my friend and I did an experiment on this and we tested water, Orange Juice, coca cola, olive oil, and syrup. It turns out that the denser the liquid the further the magnets attracted to each other. We weren't sure why this happened, but we concluded that we thought it was because the dense liquids may have obtained its own magnetism and gave the liquid a magnetic field

Answer 2

Magnetic liquids aren't magnetic themselves, but are a solution of magnetic particles in a base liquid. An example of this is certain high-performance car suspensions - the oil in the shock absorbers has iron particles suspended in it. Applying a magnetic field changes the viscosity of the oil, altering the handling of the car. You can make your own magnetic fluid at home by mixing laserjet print toner with water or light oil (like cooking oil), but it will stain like crazy.

Answer 3

Permanent magnets, like bar magnets and horseshoe magnets, create magnetic fields regardless of their surroundings. Many common substances (water, wood, most plastics, some metals) have very weak magnetic properties, and the magnetic fields penetrate them nearly unchanged. Some materials affect the magnetic field quite a bit. Iron nails, for instance, draw magnetic field lines towards them, where they travel for a bit, and then come out the other side on their way to the other pole of your magnet. Putting an iron bar across the poles of a horseshoe magnet will weaken the magnetic field far away from the magnet because more of it goes through the iron bar and less to farther places.

Some liquids have similar effects. You can make a liquid consisting of a suspension of small iron filings in a gooey fluid (water won't work -- the iron will just settle out to the bottom). Gooey oil might do the job better. This liquid acts a lot like the iron nail above. If you put a magnet close to the surface of the liquid, a little hill will form on the surface as bits of the liquid are attracted to the magnet, while gravity wants to hold it down. If you immerse the magnet in such a liquid, more of the field lines will want to stay within the liquid than escape, so you might say that the magnet isn't "working as well" (even though it is, it's just the liquid getting in the way of the magnet's field far away). You may have a tough time cleaning this liquid off of your magnet (it's gooey and the magnet likes to stick to it).

Answer 4

All of them (assuming they are strong enough)

Answer 5

yes,v can but not basic liquid we need to make liqyid with less Brownian moments but still a colloidal ferromagnetic liquid solution

Answer 6

A magnetic liquid is called ferrofluids
