A couple of questions in physics (magnetism and fluids)

Topics / Questions
Added 16 comments
I want to experiment with liquids and magnetism. But I don’t know if that will work out. There are a couple of questions.



For example, we take a coil and instead of a metal rod we insert a vessel with water into it, we connect an alternating voltage. Will the liquid (vessel with water) become magnetic. As a liquid, you can use an electrolyte with a battery, salt water, etc.

If yes, then in theory this way you can make an electromagnetic pump?

You can also make a hydraulic-magnetic generator, that is, pass water in portions through a magnetic field and receive an electric current. And indeed this phenomenon opens up very broad opportunities for creativity.

Is it real or not? So that the fluid is magnetized? That is, we create Foucault currents in water and woo-a-la.

ohh, well, then I'm not the only one, it pleases) Thanks for the link (MHD generator), I dig a lot of information. Now even more interested.




In general, I’m very interested in such stuff, unconventional, innovative :)

why tricky? belay

Well, because you want to invent the MHD generator. Of which many have already been invented and laid out on shelves. In Soviet times, an office was organized for this case (an institute with 3 floors), which wrote order papers, etc. But the prototype itself was not created - there wasn’t enough specialists and specialists.At the Moscow Institute, an experimental model betrayed something (hopes) ... That was the end. And they wanted a working fluid - plasma ...

yes by itself. But the acid with the battery conducts the current very well. It is clear that it is not practical, this is not the question.

This is sooo impractical! Distilled water is NOT a current conductor! But water, for example, from a tap, with salts / pipes dissolved in it, is a weak conductor, but of course weak ... You can of course thump salt, various chemicals there, but the water will be too weak a conductor for this purpose! There will be a lot of resistance and as a result, you will get a maximum boiler! Yes, and think, for an electromagnet you will need a lot of skeins of water ... At least 50 Current just won’t go! I tell you, as an 8th grade student!

: winked: Dear bro! You somehow called me a genius (I think you remember). I told you that you do not know anything about them.
Remember my young "kulibin": - EVERYTHING IS BRIEF, SIMPLY !. Let it be a magnet or a rope, or a wand. Genius - in simplicity !!! : winked:

By the way, you can make a coil, but instead of using a wire, use a hose with the same water (electrolyte) Water - a current conductor, will form a magnetic field. Of course, I am silent about utility, but for me to think and experiment, the topic is interesting to me.

well, yes, in order to tie a rope to a knife, you don’t need to know physics: wink: So it’s better than yours.

: wink: C'mon, is the "hydraulic" generator straight? We’ll have to make friends with physics. And then he himself will "fall off" (generator).

yes then 100%)) There are still special magnetic fluids based on a crushed ferromagnet :) An interesting topic, in my opinion, I will chemistry. I want to try to create a "hydraulic generator".

Thank you for helping with the spelling of the word "Woo-a-la" just in the article I wrote differently, even corrected ...
Maybe if instead of water we use steel filings in water, then it will work

Read the basics of physics, you probably will not be here
