 Nyorai mberi kweiyi ndima - Muzhizha ra1889, Tesla akaenda ku1889 Exposition UniversellemuParis uye akadzidza nezvemiedzo yaHeinrich Hertz ya18861888 iyo yakaratidza kuvapo kwemwaranzi yemagetsi, kubatanidza masaisai eredhiyo. Tesla akawana kuwanwa kutsva uku kuzorodza uye akasarudza kukuongorora zvizere zvikuru. Achidzokorora, uye achiwedzera, kuedza uku, Tesla akaedza kupa simba kumucheka weRuhmkorff nechinoshandura magetsi chinomhanya zvikuru chaakanga ave achigadzira sechikamu chechirongwa chakanatsiridzwa chechiedza chechiedza asi akawana kuti simba repamusoro-frequency rakapisa simbi yenyukireya uye rakanyungudutsa insulation pakati pezvinyorwa zvepakutanga uye zvechipiri mumucheka. Kuti agadzirise chinetso ichi Tesla akauya nechinoshandura chake chinodengenyeka, chine mukaha wemhepo panzvimbo pechinhu chinodzivirira pakati pemakona okutanga neepashure uye musimboti wesimbi waigona kutamisirwa kunzvimbo dzakasiyana-siyana mukati kana kuti kunze kwecoil. Yakazonzi coil yaTesla, yaizoshandiswa kugadzira magetsi emagetsi akakwirira-voltage, emagetsi akaderera-zvino, emagetsi akaderera-zvino, emagetsi akaderera-zvino. Aizoshandisa iyi resonant transformer circuit mubasa rake remagetsi risina waya gare gare.
