Polyethylene teraphlate coated magnet update
Magnet has survived 6months in salt water whit absolutely no changes and in total about a 3weeks in body. in nutshel its a 3x1.5mm magnet whit gold coating from factory and on top of it has Pet coating that i have made
i have now re implanted this piece of beaty into the pad of my ring finger.

half time of pure Pet in human body is around 15years, that means in 15 years there coating will be half as thick.
i havent worked whit the hdpe coatings because this magnet is enough for me.
hdpe would offer a lifetime implant magnet.
i have 1 magnet coated in hdpe sitting in salt water or i mean it has been sitting in salt water for about 7 months and nothings has changed so thermoplastics in my opinion is the best coating that you can make at home easily.
like i said before its thin and uniform and protects the magnet against everything.

How did you suspend the magnet in the molten PET so that there would be an even coating on all sides?
now we continue making it to look like a implant so we start by sanding it whit different grits of sandpaper, stopping at maybe 1000grit and then heating the magnet few times from different orientations because that will make the pet even out and smooth so no polishing is required, heating it up makes the coating perfect and gives it almost like factory made look. i know its hard to understand what im trying to tell here because english isnt my first language but was you start experimenting by yourself you quickly get what im telling here:D
for me this was a really nice project, it combined many hours of research on plastics and many maany hours on thinking of how to make a good coating, this project also combined some electric work and implantation itself so i have learned quite alot of new stuff.
Pet is easy to work on and makes air free magnets really easily and should be a problem free implant for atleast 15years if the coating you made was perfect enough.
as whit hdpe making a fully air free magnet is really hard but i succeeded anyways.
hdpe is also hard to grind down whit sandpaper but comparing these plastics you have to keep in mind that hdpe will last for ever in your body if thats what your looking for.
I was able to understand everything you said perfectly clearly. Your english is better than many english speakers I know (especially online). Thanks for the detailed rundown. I'm engaged in some other projects at the moment, but this is definitely on my docket to try out. I've been wanting to make a magnetizer for awhile now.
yeah my magnetizer turned out to be really good and usefull, easy to experiment whit magnet coating and like i said in my previous posts the magnets also got little more powerfull than from factory8)
