Instead of using coating/encapsulation of neodynium magnets has anybody ever found a biocompatible alloy like a variation of stainless-steel that has comparable retentivity to neodynium - lets say you would be able to get something with 20% retentivity of a N52. And to fix the low coercivity you would just magnetize the magnet inside the finger using an electromagnet whenever it demagnetises (like every hour/day/week or so)?

Let’s assume this special alloy is totally safe, and is 20% as “powerful” as n52.
I’m no expert, but I’d argue that you wouldn’t be able to feel it (sensing) or lift more than a paperclip or two.
Anyone have experience with super weak magents?
