How much time will the Magnetic Energy will be

Yes magnet looses its power with passage of time. After many years, it becomes simple iron with no magnetic field.

Yes it will reduce slowly slowly but in linear system but elctro operated will not be reduced.

I want to know is there end for the magnetic energy between two magnets. Will the energy in magnet will reduce in increase of time duration?

Sorry I don't have answer for this question. I could have answered this question if asked few years before (in my school days). Anyway I will try to find.

I think it will be constant. It will not increase or decrease.

I too think the same. It wont change.

Apparently there are permanent magnets too like the colorful pictures with a magnet , that we put on the fridge door...hope this link helps you !

I think it reduces with time. I have seen the magnet become useless with the time. :blink:
