Tiny neodymium magnets for magnajoints

Tiny neodymium magnets for magnajoints
Posted in
Custom WorkstationFor you experienced customizers out there,
What magnets do you use for "magna joints"?
I found some 1/8" diameter, 1/16" height cylindrical neodymium magnets by Magcraft, a pack of 100 for $8.99 at Amazon.
Are there even smaller ones out there? Or better deals??
My current intent is to make removable armor parts (chest plates, forearm guards), and possibly neck joints for removable heads, as explained in the magnajoint tutorial by Jin.
Any input will be appreciated!
Thanks,
Aquila08

Please wait...

Thanks for the tip about advantages of epoxy-coated magnets!
I will definitely try some out.
You might want to include that tidbit of information in the magna joint tutorial, together with the link to the magnet store.
I'm sure newbies would appreciate that very much!
There are quite a few very tiny magnets at KJmagnetics, and I am very thrilled with my purchase!
The price was reasonable, too. I got some discs, cylinders, and cubes (all very tiny, being 1/16" in at least one dimension) to start with, plus a 3/16" diameter ball magnet. Making magnajoints will be fun!
One thing to note though, for people who aren't familiar with neodymium magnets--
the product manual states that Neodymium magnets will lose their magnetic property if exposed to temperature higher than 80C (!), and in fact,
should not be burned because it will release some toxic gas.
So embedding the magnets in polymer clay then baking/boiling the clay won't work...
(the polymer clay shrinks anyway, so I guess that by itself may cause a cracking problem with the embedded magnets...)
No biggie though. I guess I will use Aves Fixit Sculpt or Magic Sculp for making neodymium magnet-embedded parts...
Anyway. Thought I would update, in case there are other newbies out there also looking for magnets.
Thanks for the posts!

The link to KJ magnetics is really handy. There aren't too many magnets that are small enough, but B3301 (3/16"x3/16"x1/32" thick) flat ones look useful.
As for weight, no problem there-- the armor parts should be very light, and there won't be much torque on the point of contact with the magnet, either.
I will just have to give it a try& see.
