AI Thread Summary
Eddy currents are induced in metals when exposed to a changing magnetic field, leading to internal heating. In the case of a galvanometer's metallic core, it does not experience eddy currents despite moving in a magnetic field. This is because the core typically remains in a steady magnetic field rather than a changing one. The discussion highlights the importance of understanding the conditions under which eddy currents are generated. Thus, the lack of eddy currents in the galvanometer's core can be attributed to the stability of the magnetic field it operates within.

There aren't any eddy currents in the metallic core of the galvanometer , Although it moves in a magnetic field? If it's right , why?

Welcome to the PF. :smile:

What reading have you done about eddy currents? What are the Relevant Equations?

Thanks! ... Eddy currents are induced in a metal when it feels a changing magnetic field . Then its internal temperature gets high and startes to melt . we apply that to the induction furnace... That's all what I knew about them .

Thread 'Question about pressure of a liquid'

I am looking at pressure in liquids and I am testing my idea. The vertical tube is 100m, the contraption is filled with water. The vertical tube is very thin(maybe 1mm^2 cross section). The area of the base is ~100m^2. Will he top half be launched in the air if suddenly it cracked?- assuming its light enough. I want to test my idea that if I had a thin long ruber tube that I lifted up, then the pressure at "red lines" will be high and that the $force = pressure * area$ would be massive...

Thread 'Why is the 3 body problem unsolvable? And what will happen if someone solves it?'

I feel it should be solvable we just need to find a perfect pattern, and there will be a general pattern since the forces acting are based on a single function, so..... you can't actually say it is unsolvable right? Cause imaging 3 bodies actually existed somwhere in this universe then nature isn't gonna wait till we predict it! And yea I have checked in many places that tiny changes cause large changes so it becomes chaos........ but still I just can't accept that it is impossible to solve...
