I'm currently designing my next coil, which I think will be a magnifier. I haven't been able to find anything really good on magnifiers, so I figured I'd ask here. What I need to know is: do the coils need to be anything specific in terms of wavelength? Also, does anyone have an equation to give the approximate output voltage? --Mr. Postman (Doug Brunner) <<mailto:dabrunner@earthlink.net>dabrunner@earthlink.net>
