Hi Guys,
Can anyone help me find some neo magnets measuring 50mm (long) x 3.5mm (wide) x 2mm (thick)?
I want to try and modify an existing tweeter that has spaces in the frame for these. They could be 3mm wide if it is more common. I can only find 10mm wide. They must be common though as I have seen these long thin sticks in B&G, Hi-Vi and OEM planar tweeters.

would love to have some as well, in neo 🙂 thin magnets are britle and break easy thats why they are not common. only on special order. and then you ahve to get many of them. usually shops wont risk it
Here you can get 3,5x2x30mm or 25 or20mm length:NdFeB Magnet. Neodym und ferrit magnete - Shop ENES Magnet Magnete - Dauermagnete - NdFeB Magnete Quader mittel <br /> (L. 12 - 30 mm) - Strona pierwsza

So.. does it work just to stick two magnets end to end? Doesn't the break cause strange things to happen in the field?
you can simulate this pretty easy in femm, there is a How to somehwere on this forum. its pretty nice. you can exaclty see what happens when.
if ur mnagnet top are north and bottom are south, at the ends they dont want to be against eachother since north rejects north (and you dont want to flip them). but even for me i hope somone can confirm that 🙂 haha

That's right as I've just tried it yesterday.
I tried FEM once before and gave up quickly. I guess a guide would be helpful!

Hi There,
I did a little experiment were I made a magnetometer to find the effects of the gap between end stacked magnets and that can be found here,

Also, I did find out with the thing that, everytime you double the stack size (thickness) you double the total strength of the Magnetic Flux.
Just like connecting batteries in series.
