HELP! Demagnetization
HELP! Demagnetization
(OP)
My questions are similar to one in another thread. In my application, I'm using two rare-earth magnets inside a shaft, same poles touching to repel each other (thus moving a rod inside the shaft)and then bringing them together again (no impact), then repelling, over and over...
1)Should I expect the magnets to demagnetize or even one of them reverse poles over time?
2)If I find the rare-earth magnets to be too strong (too hard to bring together) for my application, could I use ceramic or ferrite magnets instead, or would these be even more subject to demagnetization or reversal?
Many thanks in advance.

Temperature is one variable to consider. Any permanent magnet becomes demagnetized quicker as you approach its Curie temperature.
