100x silniejsze pole to 100x większy prąd, albo 100x więcej uzwojeń nadajnika. ] ...
Rozwijajac ten watek to tylko moge dodac ze jezeli chcemy miec 100x wiecec uzwojen przy tym samym pradzie to impedancja bedzie 100x wieksza i napiecie na cewce powinno byc 100x wieksze. Sumujac jezeli obecne wykrywacze maja napiecie na cewce 20Vpp to po pomnozeniu x100 napiecie na cewce powinno byc 2000Vpp.
Mysle ze da sie zrobic.

Na zakonczenie watku.
Omega 7.7 Khz odleglosc od cewki 20.5 cm -- 49 mVpp
25.0 cm -- 29 mVpp
28.0 cm -- 24 mVpp
30.0 cm -- 10 mVpp
wieksz odleglosc - sygnal niemirzalny
GTI2500 Standardowa cewka &.2kHz
20.5 cm -- 145 mVpp
25.0 cm -- 93 mVpp
28.0 cm -- 72 mVpp
30.0 cm -- 61 mVpp
33.0 cm -- 47 mVpp
36.0 cm -- 36 mVpp
40.0 cm -- 27 mVpp
GTI2500 Duza cewka
20.5 cm -- 166 mVpp
25.0 cm -- 115 mVpp
28.0 cm -- 89 mVpp
30.0 cm -- 77 mVpp
33.0 cm -- 62 mVpp
36.0 cm -- 50 mVpp
40.0 cm -- 37 mVpp
Nie chce mi sie juz spierac czy to ma sens czy nie - pomiary sa praktyczne, bezinwazyjne, proste i powtarzalne. Co te pomiary reprezantuja to mozna doczytac w ksiazkach.

Witam,

Pomiar z odległości ma sens - z przysłanych zdjęć to nie wynikało.
