IF two magnets were placed so they couldn't reach each other, in any way, only pull itself towards it, Would the magnets at any point "lose" there attraction to each other?

I don't believe magnets lose there charge over time, so I would say no.

Alright, i'll have a few more answers and then get this closed..

Damn science assignment! -.-

 

[Terrio]

Yea magnets lose their charge over time
All they are is -,+ charged

And yea post more!

 

[George_mybb_import13408]

Well, I know that they're -,+ but i was wondering if they do and at what rate?

 

[Relapse]

Here's a pretty good answer I found

Ok, What if i was to electromagnetically charge the magnets from time to time, Would that, In theory, Make my magnets run forever?

 

[Prohit]

I belive they wouldn't, therfore my answer is No.

You can't just say no without proof.. -.-

Heres some really good answers

How are magnets made?

Modern magnet materials are made through casting, pressing and sintering, compression bonding, injection molding, extruding, or calendering processes.


How permanent is a magnet's strength?

If a magnet is stored away from power lines, other magnets, high temperatures, and other factors that adversely affect the magnet, it will retain its magnetism essentially forever.


Will magnets lose their power over time?

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.


What might affect a magnet's strength?

The factors can affect a magnet's strength:


Heat



Radiation

Strong electrical currents in close proximity to the magnet

Other magnets in close proximity to the magnet

(Neo magnets will corrode in high humidity environments unless they have a protective coating.)


Shock and vibration do not affect modern magnet materials, unless sufficient to physically damage the material.


How does a magnet's strength drop off over distance?

The strength of a magnetic field drops off roughly exponentially over distance.

Here is an example of how the field (measured in Gauss) drops off with distance for a Samarium Cobalt Grade 18 disc magnet which is 1" in diameter and 1/2 " long.

Of course they lose charge, if they attract to anything then it is transferring electrons, you silly sally

Alright, Thanks guys.. I guess this can be closed now
