One Way Magnetic Shielding - The Holy Grail

[Megaverse]

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,

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.

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.
