A few biomagnet questions
Hello everyone, I am new to the bio hacking community, but I have been experimenting with electronics, circuitry, and building all sorts of stuff including, welding frames for different projects, forging, and blacksmithing, and have been extremely content with that for quite some time. Then I discovered the community of grinders, and people seeking to enhance there senses in very creative ways, suddenly I wasn't content with my past haha. So I'm planning to implant a magnet into my finger in the very near future as a start. I have a few questions I couldn't find very good or easily understandable answers to. 1 Cylinder magnets VS disk magnets
1 a Can you still sense magnetic fields very well with a cylinder magnet?
1 b Are cylinder magnets noticeably bulkier once implanted?
2 If purchased from a online magnet supplier, is there any special things to make note of to the supplier, specifically in the coating process, to reduce demagnetisation?
Also please tell me if you have any ideas of experimental coatings, or implanting methods and such. I have some spare time and would love to attempt some new projects in the future.
Thanks for reading,
Regards, HalfHuman.

As for demagnetizion, the only thing to worry about is the grade of the magnet. People losing sensitivity over time has to do with factors in the nerves rather than demagnetion, which takes centuries to occur.
@nothot Ok thank you so much for clearing that up. :)
That being said, you don't want them so small that you can't feel them very well. I personally have had a magnet that was too small to sense well with it. On the other hand, I have a larger "lifting magnet" implanted in the webbing between my thumb and forefinger. Despite its larger size and being in a spot thought to be less sensitive than a fingertip, it is actually almost as good at sensing as my best sensing magnet, and more sensitive than my other sensing magnet.
@nothot I would advise you reconsider trying an implanted stack. The magnets will most likely slide against each other and wear out the coating leading to a failure. Even if you were very careful with them just slight movements over time will almost certainly lead to failure. You have to remember that a TiN coating will be mere microns thick and while this might not be a problem when sitting in flesh, having constant contact with a hard surface won't be good for it.
Thanks @Beano @Nothot and @Cassox you've helped clear a lot up, thank you! One more question Im currently having. The magnet suppliers I've contacted said they don't do parylene coatings as its to hard to create a strong bond. Would a coating of (Ni-Cu-Ni) followed by a coating of TiN and Gold be sufficient?
@Cassox Oh well thats really annoying, can the chances of this be decreased by having multiple layers of TiN, or offering to pay extra if its coated well? Or anything?
@Beano I didn’t think about them grinding together like that. However, I did think about epoxy coating them together (similar to @Cassox’s resin experiments). You think that will cause any issues?
Very interesting Idea @nothot Ill be very interested in your results.
@nothot, what company did you you purchase your magnets from, if you don't mind me asking? The ones I've contacted have either been way over priced or they don't supply to where I'm located.
@SimplyTom From what I've seen gold coated magnets have a far lower success rate than most biocompatible coating, like silicon, or better TiN or even better parylene. but hardly any companies do parylene...
@SimplyTom Yeah its so hard to find someone do do coatings for biomagnets. The only issue with gold it how soft the metal is, and how quickly it wears. And when you coat it your only a layer thats a few microns thick, even with multiple coatings id worry a but about how long you could implant it before having to remove it. But experimentation is what will progress this community so I hope it goes well. :)
Have you seen when Cody'sLab on youtube when he tried it? If not id recommend watching it. :)
@SimplyTom I think more coats rather than longer might work better, but I'm no expert on the subject. Keep up the research I'm curios with what you come up with. :)
(The only shape they have is 3mm x 1mm)

@nothot Thanks so much! Ill be sure to contact them, and read your post.
