Close proximity magnets and demagnetism
Close proximity magnets and demagnetism
(OP)
Hi all,
My first post here.
I am looking to use two strong magnets, to repel each other, in close proximity.
Neodymium, same strength, same dimensions
They will not touch, but over time will the close proximity demagnetise them?
Heat is no issue and they will not be hammered in anyway, one will revolve (but not change position), while the other stays static
Any help would be greatly appreciated
Kindest Regards
Surreall

Will the gap between them fluctuate? if so then you will have a bit more demag over time. Even slight changes in temperature will cause significant demag.

How long can i expect them to take to demagnatise? hours? days? years?
Heat change would be around 2 or 3 degrees
I am looking at magnets with around a 20kg pull

Any more thoughts on how long they would last?

I keep the same idea with SREID, if the Magnets has the same magnetic properties, it is hard to be demagnitized .
