Log about fabricated stripes and accidental capillary effect!
What's wrong? As soon as I realized, that not much oil is not the case, I've imagined this picture:
- On top you can see previous structure. Oil stays in place, because it is pushed by epoxy from two sides
- Bottom is a new version, there is big air gap. And come on! Epoxy pushes oil somewhere!
How queer! But looks reasonable after all
Now main target is to find a way how to prevent it, because new structure looks promising and bends not so bad even with this major flaw in design. I made a wonderful GIMPed picture of that:
Of course I had only one stripe which bends well, so I mirrored it on this picture, just to show how it would be then contracted. I don't know why, but I like how "geometrically" it looks : )
Also I found a core for electromagnet, and designed a coilformer for test purposes:
