Should I abandon my mag motor project because of repulsion killing power

[hoarybat]

can you draw a picture of your motor setup?
i.e. - how the magnets are placed rotor and stator to cause continuous rotation?

I have to get the magnets on.  Though I have stabilized my rotor it is out of whack, low/high in some areas.  I have a lot of adjustments to make.  Also I need to put some stabilization wheels floating on the top just incase it decides to lean.  Once it does this it slows and stops.  The thing has to be totally level.  Once I have it running and if it works I will inform.  So some say replusion won't kill the magnets especially Neo's but what do u guys think about sm0ky2's comments about repulsion killing magnets?  I hear more people saying no it won't but have seen many say it will.  I guess the only way to find out is to get it going and see if there is a decrease in rpm's overtime.  If I get it going!  thanks

actually, that was someone else's comment.
i have thus far refrained from giving my opinion on that.

but , if you want it, here goes:::

the ammount of magnetic energy (Teslas) required to alter the magnitization of a material is known as its coercivity.
this is not to be confused with permeability (the ammount of mangetic energy the material will take on)

this coercivity value, is probably the main determining factor when determining how much your field will diminish.
some materials hold their magnetic energy better than others.

assuming the two opposing magnets are equal in strength (flux density) the two will have equal effects on one another. both fields diminishing to the same degree, over x time.

if one magnet is stronger than the other, the stronger magnet will not lose any of its field, only the smaller one.

if the coercivity of the material is greater than its permeability
such as is the case in neos and certain ferroceramics, then the field it produces is not strong enough to adversly affect the opposing magnet. - thus neos (in most cases) are safe when arranged in this manner.

for example, the read/write arm inside a computer HardDrive, is always reset back to the original position by magnetic repulsion.
a tiny neo is stuck to the back of the arm, and repels against the larger neos that bias the field of the write-mechanism.
this occurs millions of times throughout the harddrives life, and the neo magnet on the back end of the arm never dies.

so, in conclusion - it depends on the magnets (and sometimes how they are used),

'soft' ceramics like the rectangles you can commonly buy anywhere, may lose or weaken their field strength if used in repulsion over long periods of time.

hard ceramics, such as those found in microwave magnetrons can be left in repulsion for decades without harming each other.

most of your neos, and some of the cobalt-compounds (alnico) are perfectly safe.

aynways, thats the simplified version, there are many other factors not mentioned here, that may come into play but thats for a whole other topic area...

That was very well put.  Your information is very invigorating and welcomed.  Could be a couple more weeks or so before my first valid attempt since the improvements of this junkyard parts wood setup.  Today I also started putting a wood inside circle 360 degree piece which I will have to cut in passes with a stationary circular saw adjusting it by 1/8th of an inch intervals to shave a 1.5 circle to accommodate a future direct drive alternator (should this thing keep going) so I can put a load on it and see if it will still spin with a load.  Using belts and pulleys causes more friction loss and I already have too much with my crude setup.  Thanks again really enjoy the forum and their members...
