Is making most, but not all people feel a sensation in their hand an empirical effect? ***Yes.
Additionally some people feel some of my designs and not others. ***Then you can go into Edisonian experimentation mode to find the design that generates the most effect. But I guess making people feel it without any psychological component removes the subjective aspect? ***Absolutely. You use a double blind experiment where they pass their hand through a completely inert "coil" and then through one of your coils and they report what they feel. If the effect is real, it will show up as happening on your own coil more than 90% of the time. Or the dramatic health effects? Of course any claim made in this direction will have the charge that it is just a testimonial and not considered as scientific evidence. Really that makes me sound like a snake oil salesman so I often ignore it as evidence. ***It's okay to act like a snake oil salesman for a while. Here's what I'd do if I were in your shoes. I'd pay the $50 fee for setting up a booth at the local farmer's market, set up that double blind study I mentioned, and video record every person involved. And sell coils at the booth. Try various claims to see if one or two in particular help sell better. It would be a fun way to spend Saturdays. And you make money all the while that you are investigating this anomaly. If the coil is small enough to be implemented into a bracelet you could sell it as a "healing bracelet". It's no more snake oil sales-like than those guys who claim to be psychics. People who feel the effect will be inclined to buy bracelets. There, now you're in the Saturday Jewelry business...
