    imagining fields (not forces,

    Yeah that thing. Except that they were dubbed “magnetic lines of force”. Also, I remember it being separately explained that even though they were called that, they didn’t represent the direction of force (of course not, or you’d not need the right-hand-rule and left-hand-rule).

    Looking at the iron shavings though, it seemed more like low potential energy regions/ stable regions.

    Also it give a feeling of being analogous to fringe patterns.

    For anyone whose magnet related memories are not filled with various line illustrations of the forces, that’s probably it.

    And even though my head is full of those illustrations, I don’t seem to understand how the iron fillings and ferrofluids make the shapes they do instead of just sticking to the magnet. And I am too lazy to do the maths to make myself understand.





  • Not really.

    They are just getting rid of any and every liberty that any reasonable society would provide.

    Not the rights though. We never had such rights. We just didn’t realise those were needed to be written down because others didn’t violate those expectations.


    Even in an anarchy, without any written rights, we would have those liberties, given a reasonable society. Just not here.
