Behavior of a Magnetized Ferrous Material

[James08]

If a ferrous material is magnetized using a solenoid, would the magnetic strength of the material fluctuate over the next few hours? How long would it take for the magnetic strength of the material be stabilized?

I posted in the other forum, I saw it first.
But I can say it again.

Provided that you are doing nothing to this part, it is just sitting there.
The field should stabilize within seconds.
I have seen changes measurable over minutes, but they were realted to heating during magnetization and the time that it took the part to cool.

Corrosion never sleeps, but it can be managed.
