Demagnetization risk of Neo magnets in repel mode?

[Honk]

There is a lot of people telling us that placing magnets in repel mode will demagnetize them.
But many of those people have used inferior magnets in their test, like cheap ferrite.
And then we hear over and over again that repelling magnets will demagnetize them.
But that might not be true if you are careful and use neomagnets of the same size,
shape and strength in repel mode. Then the fields are equal in strength.

Please read the question at this link. It explains my concern.

I think we have to sort out the risk when using good quality NdFeB magnets.

So, if we have two equally strong neo magnets of the same size and shape
they should be able to operate in repelling mode without demagnetization.

I have attached a demagnetization graph on several types of magnets.
But I have trouble understanding how to read it. Can someone here explain
how to see what type of field it takes to demagnetize the N38 in the graph?
It might clarify wether it can withstand or not to be demagnetized of a similar
external field as the N38 holds.

The above sentence makes absolutely no sense because the noun "magnet" is missing an adjective.

If people would simply ask NEO manufacturers this question instead of speculating, they would have the answer:

Two NEO magnet can not weaken or demagnitize each other in repel mode.  If not heated excessively or violently vibrated, the great-great-grandchildren of your great-great-grandchildren will not be able to measure any weakening of NEOs in repell mode.

People who say that NEOs can demagnetize themselves, usually can not tie their shoes on in the morning.

End of discussion.

Earl,

Did your information come from a Neo manufacturer or have you been working for one?
I have not noticed any weakness from using them in a working magnet motor (using my design).  Do you have any figures when magnets are used at certain velocities with one another?  Or does this make any difference to the "pinning material" within the magnet?

Thanks.

My theory is that a stronger magnet will demagnetize the weaker one... If the magnets are all the same material, shape, size and strenght no demagnetization should take place. no matter what configuration you place them in...

That's my point exactly, but it would be nice to have some calculations or graph understanding
to back this idea instead of just guessing.
I'd like to design a Wankel motor at repel mode but then I need to know more about the risks.

Hey all of you guys out there. Please tell us what you know about this subject. (Other than guesses)
