I'd like to try two rings: one magnetized through the thickness, and the other magnetized through the diameter. That would let me sense two orthogonal vectors from the surrounding field.
Have you been able to find anything that would do this, as this would be quite incredible to feel. You can measure magnetic fields with solenoids with wrapped wire, but this would be quite the impractical solution for a ring.
I've placed two orders from this site over the past 7 years and it went great both times. The magnets are incredibly strong. These rings will definitely be in my next order
I would hesitate to wear a solenoid, due to the induced current from magnetic fields.
