Using a piece of magnetic field viewing film to check the pole orientation of various magnets. Also, what happened to that neodymium magnet I soldered a wire to?

Everyone thinks iron filings follow the magnetic field "lines", but the field line idea is completely misunderstood. Science uses lines to illustrate the gradient on paper. The field itself with no mass is actually smooth with no detectable lines in it. The filings each individually become little magnets in a field by channeling and concentrating the field through itself with north and south poles that convince other mass to do the same. A group of filings line up each other's poles CREATING lines that were not there in the field by itself. It gets more complicated in the spacing mechanism, and I'm sure no one can explain that yet. Modern science still struggles with "why" it's perpendicular to electricity.
I'd love to see multiple electromagnets using this green film. What would it look like if you varied the strength of multiple electro magnets?
Basically when you soldered it, that part reached the curies temperature, so the ferrite material was in "magnetic flux" where the molecules can be set in place better. So all the molecules will have a randommagnetic orientation (that is what we call demagnetisation, because magnetisation is just the alignment of them magnetic fields (every metal is electromagnetic). When making a magnet, they heat the material to the curie point and use an extremely strong electromagnet to align the orientations all the same way.
That makes perfect sense? It's like seeing a card facing you versus 90° away.
Where can we find magnetic film. Can we find in fotocopy shop?
Can you send a link where to buy that paper

Heat kills magnets.
You can really see the effect that the heat had to the magnet, it clearly had removed all the lines of force from that section. Neat! If it really had "flipped the poles" of that section, there would be a distinct black area for that newly heated (soldered) section, with a white border around it.
I wish these videos would get to yhe point . I'm trying to find specific information and trawling through so many videos and these youtibers don't half like the sound of their voice. So much waffle.
So the EMF field detector, Alien vision in older Alien vs Predator games, is a dumb vision? Why not have a aura vision?

Those viewers work much better if you allow the back lighting to come thru . Much Better ! View from the Matt side. When you heated the magnet you raised the Atoms to a higher energy state. When metal is heated to the Red Hot State it turns RED because the Electrons are boiling off. When ever a Electron alters it's valiance bond a Photon is emitted. The corresponding Electrons were allowed to free float at will. The Electrons were no longer Aligned is the singular directions.
