Inverted Ferro Fluid Quadrupole

thats a whole lotta nothin.

Question! If you completely fill an air-tight cylindrical container with the magnetic fluid, will it react like a normal solid magnet having North and South Poles? How can we achieve it? I want to know please, Thanks.

wow your smart lol

No it wont because one end isn't heavier than another to point north or south it wouldn't help in any way as a compass or showing the north and south poles because both sides are the same.

Dipole magnets form due to the influence of an existing external magnetic field. You should look into the magnetizing process to learn more about how it is achieved. It's very interesting, and slightly complicated if only because of how unfamiliar we are with it. Basically, if you subjected it to a very strong dipole field, it would possibly "remember" the shape of that field. After you remove it from the influence of the strong field, it would likely "forget" that orientation...

Go to Wikipedia and look up "ferrofluid" and "superparamagnetic" (also "paramagnetic" and "ferromagnetic"). The info there suggests that ferrofluids are superparamagnetic. They don't behave like a normal magnet (ferromagnet), maintaining their own magnetic field. So no North/South on their own. They only align in the presence of an external magnetic field.

Ferrofluid in itself is not magnetic. I believe it consists of very tiny iron particles, possibly nano, in a specific oil. I imagine , as you described, it would behave like iron shaped like the container and just be ttracted to the magnet as a whole. SS

This needs music! It is cool though.

wtf?
