Magnets & Loss
I've heard that magnets lose their polarities when they
are exposed constantly to other magnets. Is this true?
Will Magnets Interacting With Magnets Cause Pole Loss?
I have never heard of
magnets losing there poles/polarities from magnets interacting with
other magnets over time. I looked that up and I could not find
anything that supported your question one way or the other.
Possibly you were asking, do magnets lose their strength when
interacting with other magnets over a period of time?
is not in on this one. Some say yes, while others say
no. It also depends of what kind of magnets you are
using, as by no means are all magnets the same!
What I can
tell you though is that all of my rare Earth magnets I
have today are still incredibly strong. I put my magnets
through very tough tests where like poles as well as
opposite poles pass each other repeatedly within less
than an inch of each other. Yet, all of my magnets work just fine.
day I had a magnet the size of a postcard in my hand and
I also had a refrigerator that was also 4"x6" in size
that had a picture of a lake on it. Just for the fun of
it, I allowed the two magnets to run across each other
so I could feel the effects of the force. Little did I
know at the time that when it came time to stick the
picture magnet back onto the refrigerator that the
picture magnet would no longer have the strength to
stick to the steel.
magnets was ceramic and the other was the worlds
strangest magnet, and it simply killed the thin picture
Here are a
some thing to remember:
Banging, dropping, hitting, and hammering magnets makes
them lose their strength.
Heat makes magnets lose there strength.
magnets lose there strength.
electrical currents in close proximity to a magnet
lose there strength.
shock and vibration do not affect modern magnet
materials, unless sufficient to physically damage the
The best way
to maintain the magnet strength is to put what is
called, a 'keeper' on it. A keeper is a thick piece of
steel plate and cut to the exact size of the the pole(s)
of the magnet. When the magnet is not in use, the steel
plate is stuck to each pole. In the event of a horseshoe
magnet, one plate fits all the way across both poles.
If need be,
just fine a big piece of steel, even a steel I-beam, and
just let the magnets stick there until you need them
again. Just remember not to let the magnet crash into
each other as you do this. lol :~)
I hope I've answered your question.
