Hi Jacob,

There is no place in the universe that exists without some sort of magnetice interference.

Magnetism is a property of polarized atoms. After a sufficeint amount of coherency loss the magnet loses its "pull." The pull is based upon the coherency of countless tiny waveforms emitting from the fields of the nuclei.

Exposure to any strong field will shorten the life of a magnet.

Here is what happens:

The magnets atoms interact with other coherent waves of differing frequency, shape etc. In this interaction their own directional uniformity is disrupted, breaking down its ability to bind with the iron girder based upon the diminishing field. The larger the field the more atoms a magnet can "hook" into with in-phase wave matches. Likewise with powerful waves disrupting the magnets field - it diminishes field size and strength.

That is why it is easy to speed a magnet's field decay process by putting two of the same polarity magnet ends together (++ or --), as the repelling force is caused by matching frequency waveforms now out of phase and colliding. This process realigns the atoms in a manner that they no longer work in unison, their field size diminishes and eventually just become any other iron atoms.

ET's reference about temperature is true, colder environments help magnets - but only because cold environments generally have low frequencies. The low frequency waves dont interfere or degrade other fields as quickly (due to less harmonic divergence.)

A high quality 11lb magnet as you might buy from a store on earth might stay bound to an iron girder for 50 years or so before falling off - earth's own magnetic field and things like temperature changes will take their toll and can vary the field decay dramatically.
