I work in the Aggregate industry and we use ceramic magnets to pull ferrous materials out of the feed of Aggregate materials passing by on a conveyor belt.
So i have a basic knowledge about how they work, but my technical knowledge about magents is extremely lacking.
Wondering if anyone would have any theories as to why a ceramic permanent magnet would lose its strength working in a place with extremely cold temparatures? I.E. -40° C.
I know that permanent magnets become stronger when they are put in extremely cold temps, but I'm wondering if going from -40 to +20 every 24 hours for months in a row might gradually decrease the strength over time??
Any thoughts would be helpful. Thanx in advance.
