When I was little, my mom dropped me and her friends kid off at a church for arts and crafts, I was 5. We we given toilet paper rolls, pipe cleaner, glue, and some other stuff to make butterflies. I studiously started making mine, I got the wings, the antenna and asked what I was supposed to use for the legs. A full grown ass women look me right in the eye and said “Butterflies don’t have legs”.
I had seen butterflies land on flowers and latch on with legs, I was so confused how an adult wouldn’t know that.
Last year my daughter told me her grade 4 teacher had told the class “Well nobody really knows how magnets work” to which my science-obsessed daughter replied “You mean you don’t really know how magnets work!”
I confirmed to her that yes, our understanding of magnetism is about as complete as it can get. Of all the mysteries the universe has to offer, magnetism is not one of them.
For completeness, we cannot say for sure if we even exist. The universe could very well just be an imagination and nothing really matters, including the laws of physics and our understanding of magnets.
I think that’s why I could never fully latch on to atheism. To believe there is no power behind the universe is madness. Of course there’s a higher power! One whose power not only created the universe, but has determined it’s every action and outcome since creation. It is an absolute power, there is not a single atom in this universe that can go against it. It is omnipotent, it has already determined the future and it’s path can not be changed. It controls the thoughts, actions, dreams, and beliefs of every living being.
The funny thing is, for all the arguments and wars about religion, humanity has known about this God for over a millennia; and over the years our understanding of it has only grown. We even gave it an agreed upon name.
I’m addicted to solipsism. I know I’m meaningless in the grand scheme of things. But I’ve been thinking that when I die and cease to observe the universe and be aware that it exists, then what’s the point of it existing?
Okay, but, with other forces, like electricity, we understand that elections are bumping down the line and the force/motion of that can be used to do work or something.
With magnetism, it’s more like, a complete black box, we can see what happens when we do x, but we have no idea what makes it do that. Magnetism it’s measurable, we know it exists, we don’t know how it exists. We know it works, but we can’t figure out why it works.
It’s a bit like gravity. We have some good theories, but that’s about it.
Isn’t it the alignment of molecules in a material so that their electrical charges are all oriented in the same direction, thus attracting the opposite charged ions of other molecules in other objects towards the corresponding side of the magnet material? That’s why magnetism only affects materials like iron where the molecules naturally form in a uniform orientation during it’s transition from solid to liquid, and not other material that has a more random orientation.
I mean, I guess when you really boil it down, there may still be some question as to why positively charged ions are attracted to negatively charged ions in the first place. But then we’re getting into quantum mechanics which is way deeper of an answer than a grade schooler would be looking for and so far down the rabbit hole that making a claim like “we dont know how magnets work” is only true in the technical sense. And by that, I mean it holds as much truth as “we don’t know how anything works”.
It’s a bit like gravity. We have some good theories, but that’s about it.
No! That’s the point I’m trying to make! Gravity and its source truly are a mystery (aside from the basic fact that it causes mass to attract other mass, of course)
Magnetism is a well defined component of the electromagnetic force. We know what it is, where it comes from, and why it has the effect that it does. We’ve known most of this for a century! The study of electromagnetism came early to the field of physics because it’s easy to work with and understand on human scales.
To be very short, moving electricity creates magnetism; moving magnetism creates electricity. A permanent magnet is magnetic because most of the electrons are spinning the same way, creating magnetism. That’s it.
That is what you tell the grade 4 students.
Later you can teach them about magnetic domains, dipole moment, electric and magnetic fields and their relationship to radio waves etc… But these are all things we know, and I feel like it’s important that kids know that humanity has in fact mastered magnetism.
Sure there is still a lot to learn, but at this point it’s engineering, not science. Practical things like magnetic alloys or optimal field arrangements for motors.
Fun fact: next time you see the moon in the day, study the angle of the sunlight hitting it — it doesn’t appear to line up with the sun. This is a perspective trick based on the fact the sun is way further away than the moon yet we perceive them the same distance. And no I cannot intuitively grasp this.
It has to do with apparent size of the sun and moon. The sun is 400 times wider than the moon and coincidentally 400 times further away, so they look the same size. With no other reference points as to how big each object is, we perceive them to be the same distance.
Stupid/inconstant adults stick in your mind. I’m lucky to have mostly had good teachers, just one teaching vowels one week taught us a, e, i, o, u, and sometimes y
Then the next week tested our learning, and marked my answer “a, e, i, o, u, sometimes y” wrong because it’s only aeiou. Sure teacher. No vowels at all in by, but the same sound at the beginning of bicycle has one.
I think they must have been reading from a book when teaching, but working from their own ideas for the test

I remember asking my teacher why you could see the moon during the day and my teacher told me you couldn’t.
This too left me very confused, because I had seen the moon that very morning from the school yard.
Last year my daughter told me her grade 4 teacher had told the class “Well nobody really knows how magnets work” to which my science-obsessed daughter replied “You mean you don’t really know how magnets work!”
I confirmed to her that yes, our understanding of magnetism is about as complete as it can get. Of all the mysteries the universe has to offer, magnetism is not one of them.
What that teacher probably wanted to say was that, while we can explain how magnetism works, no one can tell you why it happens.
Nature doesn’t have a reason to do things. There’s no ‘why’ in anything, other than ‘the laws of physics make it do so’.
For completeness, we cannot say for sure if we even exist. The universe could very well just be an imagination and nothing really matters, including the laws of physics and our understanding of magnets.
In this year alone, I’ve had so many things happen that just scream we live in a simulation, it genuinely wouldn’t even surprise me if it was true.
Either way, nature is our one true god.

We call it Physics.

Therein lies the issue. We don’t know shit about the fundamentals of magnetism, other than “it sort of just follows the rules of electricity”.
Feynman on magnets and these kind of questions.
4th grade seems to be about the right maturity level to become a huge ICP fan, so it checks out.
It’s just that magnetism is really complicated the deeper you go, and there’s nothing else to compare it to.
I don’t wanna talk to no scientists
They’re just lyin’, and getting me pissed

That bit I can at least fully comprehend. It’s the sunlight angle thing I can’t wrap my head around.
You want to know about space, you ask NASA

I’m curious how that person thought that butterflies rested… Or did they just continually flap their tiny little wings until they died?
But, I mean, you were at a church…
