Magnet Behaviors

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

RE: Magnet Behaviors

It may be better to post this question in the "Magnetic engineering" forum. Where is the fluctuating come from? the ferrous metal may have a residual magnetism depends on the metal but I have no knowledge of fluctuations.

RE: Magnet Behaviors

I assume that you are not doing anything to the material, it is just sitting there.
The field levels around it should stabilize very quickly.  Maybe a few seconds at the most.
Sometimes you can measure changes over the course of a few minutes, but I believe that most of those are related to temperature effects.  If you warm the metal during magnetization then it will take a while to cool.
