I've had good success with the "Cell Sensor" for confirming or discounting sources I've sensed with my fingernail magnets. I was surprised to find the Cell Sensor is cheaply made with through-hole components, but hey, it works. I'd love to roll my own.
On the other hand, I've had crap results with small fingernail magnets. I'm very glad I prototyped with larger magnets, because the 3mm magnets are way too small to vibrate my whole fingernail.

I am a bit late to the discussion here, since the link is already broken, but I think it's neat that this is being discussed here. About a year ago, I bought some magnets and sensors, and tried out fingernail magnets.For anyone trying out fi...in Everything elseFebruary 2012

I am indeed serious. Based on my knowledge of electronics and physics, I don't see where the electric field is coming from. I legitimately don't see how a coated magnet would transmit an electric signal. On the other hand, the 60...in MagnetsJanuary 2011

Don't these magnets work by mechanical vibration? The Wired article alleged that neodymium coated with silicon and then gold caused an electrical field, but most of what I've seen suggests that mechanical vibration is the only source of sens...in MagnetsJanuary 2011

@niko -- that's pretty awesome. The only bad thing is it looks dangerous. Which is also why it's cool. But it looks dangerous... and cool! ... I don't think I'll be any help here. -Jin AnnouncementsJanuary 2011

I also ordered the V&P magnets (from the USA) -- I ordered the 3mm (x100) and 6mm (x10) magnets for $53, the total was around $75 including S/H.I placed the order on Thursday via their order form, they emailed me the same day. They sent ...in MagnetsJanuary 2011
