Basically making permanent magnets out of non magnetic material. First thought… Is it bio-compatible?
I realize there is zilch chance of making a magnetic implant from this. It probably has a teeny tiny little magnetic field. That degrades quickly. And can only be detected on odd numbered days in even numbered years.
But… It gives me hope, plus I like to keep an eye out for tech starting to come over the horizon. Sooner or later something is gonna pan out.
