Magnet Implant Sizes, Inverse Square Law
So I have one magnet in each finger, save for my thumb, of my left hand. While they work as intended and for that I am happy, the electromagnetic field-sensing range is low. This was expected, don't get me wrong, but I'm interested in any possible mechanism of expanding the field-sensing range. Unfortunately, there's not really any stronger magnets available for implanting. However, there are larger N52 magnets available.
Anyway, I was wondering if this is even feasible. Of course, as magnet size goes up, so does the chances of it rejecting, as well as the chance of a coating failure. These are worthy risks to take in my opinion, especially for self experimentation. Whether or not I look into this is dependent on one main question, and that is if the inverse square law would make it so even a larger magnet still has a small sensing range. if hypothetically I were to implant a magnet twice the size of a normal magnet implant (3mm*1mm), assuming it didn't reject or fail, would the field sensing abilities be significantly greater than a normal sized magnet?
