Well one is glad to be of service !

Frankly tito i'm not going to comment every video you sent. There is just too much and about each can be debated both ways (either a fake or not or even don't have any pratical uses).

now i believed that you are correct sir because one of my magnet's strength was lessened because of heat, i think even a year cannot last

It's not exactly what i said or maybe I didn't make myself clear. it's each time you heat it above 80 degree celcius (there are some that resist up to 220 Celcius) that it will scramble the magnetic domain reverting them to the iron property (meaning that the magnetic domain of the magnet is not in a straight line anymore (Thus allowing the passage of the south pole to the north pole) or has bumps along the course witch makes it less strong). so if the magnet seems half depleted well it's just the magnetic domain that are let's say "melted" just to understand it's not like a half batterie that loose power in other word ...i used to think that, lol. I though it was a charge of electricity that creates the magnets ...anyway all this to say if you don't ever heat it again it will last like that for a few life time.

Or if you are pulsing them in a very very high current magnetic field, that could hurt them also.

That, I do not know but it seems quite logical.

sir i have a suspect that it uses the arrangement in HALLBACH array, JUST CORRECT ME IF I'M WRONG

I'm not sure what to say about this ...yes the hallbach array effect. Up to know it's just an experiment and no one has done anything usefull with it (that I have seen of course). Well in anycase if you wish to discuss live about some of this or if you have questions or just something new for me to learn then you could always check your private message i'll send you my MSN Id ok.

Sincerly,

@ MAG and MEG a difference of "a" and "e" sounds magnet and megnet

joke

I FEEL HIGHLIGHTED TO BOTH OF YOU SIR

THANK YOU VERY MUCH

Hey Tito
How about a small cooling fan and even an aluminum heat sink to keep them cool. Small fans in a pc such as the ones that cool smaller chips independently on the motherboard use very little power and do keep things from getting too hot.

Yes, actually i made a small radiator like style to absorb heat and it works!

i made use of a fountain motor and a couple of small hose, combined with the pc fan.
something like this:

I'm starting to wonder what the hell you are making tito ? why does your magnets heat up

Are you building an air climatizer like the last vid you showed us ? And why waste your time with cooling systems ...when you just have to buy a manget that resist like 180 degree for example (it's the same as the 80 degree example at 79 it does not damage the magnet but still it looses it's strenght temporarely) so at 179 it doesn't damage the magnet ...here's a few example:

Neo magnets resist from N35 at 80 Degree celcius to N38EH at 180 degree celcius ... If you need more than that then there is the Samarium-Cobalt rare Earth Magnets that are far more costy $$$ but resist up to 250 Celcius. Other more cheap magnets that are still at 250 celcius is the ferrite magnets: resist up to 250/280 degree celcius.

And the strongest of all (for the temperature factor) is the AlNiCo magnets ranging from 760-850 celcius ...at that temp there are a few metals all ready in liquid form, lol.

So now i'm curious to see or hear about what your trying to make tito ? ...who knows maybe I can help. I just don't know for now.

Ahh and just a random info like that apparently they don't make N32 magnets anymore because they are unstable. They don't give a result that they expect or want... I don't know really why but they stop making them (if you can still buy some i'm guessing that they have tons of that shit in store lol. like www.calamit.com who have 400 tons of magnets all ready done waiting to be sold ... ouch huh.

see ya,

Meg
Maybe Tito needs a special shape or strength of magnet for his particular situation, in which if it is degrading from heat, he needed to simply solve the heating problem.
As far as neos, there are a variety of strengths to N52. I had purchased some N52s that were weird themselves. They were 3/4 x 1/2 disks, but they were not a balanced field, being that they had a strong side to them about their diameter. This was bad for my project. I tried to orient them to achieve a balance, but they ended up a huge problem for me. But I suppose that many magnets have their differences, even from the same batch. This could be a big problem for many who delve into permanent magnet motor builds. I see that Steorn uses slide adjustments on their rotor, probably due to the same problems. In order to get better balance, many would have to be purchased then measured and matched to get better results. The whipmag was plagued with these problems also where Axle took a tremendous amount of time trying to heat and cool some to get matched sets. I'm not sure he has finished yet and it has been a while.

hi meg good day

i'm making it as a core, nothing but just a wild experiment, trying to power up a bike of my son for free.

Trying and finding some result what would happen if i heated the magnet, trying to see if it will loose some electrons it is holding and i'm trying to capture those that are loosing, still i'm in the middle of this experiment. quite funny isn't it?

actually i'm using some of them in my spark gap.

Anyway thanks for the nice info sir

I wonder if a magnetic viewing card can be inserted as a lens on a PC cam.

Magluvin · « **Reply #114 on:** January 01, 2010, 03:21:35 AM »

Onthecut
I dont think so. I have played with the viewing cards quite a bit. The card really needs close proximity to the mags to get a detailed view. Maybe if it were in macro but the mags or even moving mags may be harmful to the camera.
The cards are very helpful in determining the center of the field poles especially on round or diametrics.
I did do a cool vid on YT that shows interaction of an antigearwise stator on a whipmag rotor and there was a very focused field between them that oscillated back and forth. Neat stuff.

well @mag it's the first time i hear about that kind of problem but i think i know the why and how. when the powder is compressed and cooked in a big block (were talking almost a 2 foot block or very thick plate.) they aligns the magnetic domains in a certain desirable direction (imagine it like wood fibers that goes in one direction) and then they shop this big block or plate in pieces and they have sadly a +/- 2 degree error possible so what I think that has happened for that batch is that it has been calculated wrong in the frst place and they have been shopped down all with the same error. (well it's supposed to be rare ...).

And @Tito they are at least 2 forces in magnets there are the famous electrons and the infamous forcefield that it's another forces witch at that point i still don't know exactly what it is but anyway it's been prooven out of a doubt by many scientist that you can't get electrons from magnets but as soon as the magnet is moving then he capture the ones around them ...but it still needs to move even if it's small vibration then what i think is happening is when it moves it capture electrons in it's forces flow (like a river) and when they come in contact with a surface that can attract them more than the moving field THEN they go in the copper (for example) it could be other materials but copper is one of the best and the cheapest. ...that's what i think it doesn't mean it's true but still it kind of make sense so in bref the magnets when moved around they collect a certain number of electrons that the empty space is really full of and that's why they are some but it's not collectable other than the way standard electrical motors function now a day ?

Well if anyone has argument or complementary comments please add them ..thanks you

just wanted to ad this http://www.supermagnetman.net/index.php?cPath=54

The guy explain the temperatures, coating, size, ect... far better than me lol. just click on the green arrows. (So if you still have question I think he's a good source).

i'm on his site actually right now to ask him for a custom magnet ...usually if you demand magnets that are magnetized any other way than normal it will cost you like 3000-4000$ because the damn morons can't program their machine to cut like only a few in another position (or even worst depending on the situation they could simply use the same program and just turn the damn block) but no...it's far better to ask outrageous prices so the littles can't get anything out of the ordianary and risk to find something special huh ?

Sorry i tend to go crazy with conspiracies hehehe. anyway there's a good possibility that this guy "george" can do it so note the place if it's the case ...ok bye

Did i say something wrong/stupid ?? everybody stop putting comments all of a sudden ..?

Anyway ... I'll continues this tread like it was originally intended and it's about shielding. I have finally found a guy who sells damn magnets magnetized through the side instead of the usual thickness (for a rectangular of 2 inches long, 1 inch large and 1/4 thick it's through the 1 inch large or wide if you prefer) I buyed 4 of those to test the shielding method. just to see what can be done.
it's super magnet man... I gave the link in the previous post so check there it's in the ...err, not supply ..ahh damn I'll have to check again ...ahh OK it's in the discount section: I got this "BNDL345" ...hope I'll be able to do anything with this. IF i ever do anything that that make freakin sense THEN I'll make a video and post it ...

Just to say for those who don't know. Usually the whatever company ask that we buy the whole big block around 2 foots. It's around 3000-4000$ when you want something out of the ordinary because they get stuck with the rest of the batch. So having those magnets at 4.25$/each is not a real barging ...well not to me anyway but it's still rare to find a guy who accepts to make some or find them or whatever.

Good luck in all your projects,
