Explain the polarity alignment. Tell me what it is and why it happens.
Explain to me how a magnet holds what it holds to does what it does.
That is what you are meant to be doing.
Stop deflecting.
If you want an explanation from others, how about you admit your explanation doesn't work?
After all, you are the one who started out claiming to be able to explain them all using air.
Again, can you explain the observed polarity? Can you explain why if you take 2 magnets in an orientation that repel, turning both magnets around still results in them repelling; and if you take 2 magnets in an orientation that attract, turning both magnets around still results in them attracting?
Because with your "explanation" so far, that simply doesn't work.
A vacuum is the absence of all attached matter in the terms of what you people accept.
This cannot happen, so a vacuum is a nothing meaning for reality.
As has been repeatedly explained to you, that is not the case AT ALL!
What you are describing is known as a perfect vacuum, or ideal vacuum, which simply doesn't exist.
But in general, a vacuum does not need to be perfect.
A vacuum is simply significantly lower pressure than 1 atmosphere.
This includes a low vacuum, which goes from roughly 100th of a vacuum up to basically 1 atm.
It also includes things like UHV, which is a tiny tiny tiny fraction of an atmosphere.
