I am posting this here because I have not been able to find the answer anywhere else. I know some of you might find this quite dumb of me, since I have seen some quite learned scholars in this forum, and my question is pretty basic. I am aware I might not be in the right forum.
My question is : Do permanent magnets have a duration, and if they do, what is it aproximately and how is it measured?I know that the duration micht be different for each kind of magnets (neobydium, etc...). I am aware of the factors that cause a magnet to demagnetize (dont ask me if this is an english verb [?]) , as heat at the curie temperatue and hammering it to lossen the domains. So what I wish to know is, under unchanged conditions, will a permanent (it is just a name) magnet lose its properties? Or is it magnetic forever?
Thank you in advance for your answers
