Will neodymium magnets lose strength if they are held in repeatly attracting positions for a million/billion times? With assumption of without physical contact of both magnets with gap in between approximately ~1mm, and the frequency ~100 times a second

No, neodymium magnets will last a lifetime.The magnet will not lose its strength simply from a crack or a chip. Even if it breaks completely in half, you will simply have two magnets (with very sharp edges). If the magnets do end up with sharp, pointed or jagged edges we recommend throwing them away. If they are simply chipped or scraped up then they will probably be just fine. The biggest risk to a damaged magnet is corrosion.

Neodymium magnets have high coercive force, that it is not easy to demagnetized( lose magnetic strength), but please don't let neodymium work at very high temperature. Heavy hit will reduce the magnetic strength in fact.
I am just learning these knowledge, because I am a new salesman in a magnet manufacturer in China.
