Magnets have always fascinated me.

The previous answers are correct, permanent magnets will loose their magnetic strength because room temperature is a long away above absolute zero. As long as there is atomic vibration, the individual atoms in the magnetic domains can become un-aligned and, therefore, the magnetic strength decreases. Magnets have a Curie temperature above which they will lose all their magnetism. This is a temporary condition because magnets can be remagnetized after they lose their strength. Magnets really are fascinating.

Both in some extent. It is obvious that magnets lose there power the older they get (been explained before me) but also by use. Some magnets lose power as they hit things, so if you throw magnets at something really hard, they'll be less and less effective.

Magnets do not lose their power from overuse but they do lose power as they get older
If a magnet is dropped it can possibly lose all it's power though if it's snapped in half it will become two separate magnets

Modern magnet materials do lose a very small fraction of their magnetism over time. For Samarium Cobalt materials, for example, this has been shown to be less that 1% over a period of ten years

how long does it take for a magnet to loose it s power

I think is both?
The older they get, the atoms that produce the magnetic Field us up there available energy and are not replenished as the are in the earths core.
but faster when in constant use as they use there energy more.
However you can increase there life span by conducting electricity through them like in speakers, so it would depend on what sort of magnet you were on about?

my uncle have been given lots of of quite solid magnets with regard to the size of a million/2 a mac n cheese from a laboratory for unfastened. consistent with danger you should pass inspect the interior of reach labs on your area and ask for some.

yes as they get older
