Rangarira ndima iri pasi apa uye ipapo pindura mubvunzo gare gare mumutauro mumwe chetewo sechikamu:  Passage: Muzana ramakore rechi6 BC, muzivi wechiGiriki Thales weMiletus akaedza tsvimbo dzeamber uye izvi zvakaedza zvaiva zvidzidzo zvokutanga zvokugadzirwa kwesimba remagetsi. Kunyange zvazvo nzira iyi, yava kuzivikanwa sechinhu chinonzi triboelectric effect, ichigona kusimudza zvinhu zvakareruka zvoita kuti pave nemwenje, haina kunyatsoshanda. Kwakanga kusati kuri kutozosvikira pakagadzirwa mutsara wevoltage muzana ramakore rechigumi namasere apo manyuko anoshanda emagetsi akava anowanika. Batire remagetsi, nemwana waro wemazuva ano, bhatiri remagetsi, rinochengeta simba nemakemikari uye rinoita kuti riwanike kana richidiwa sechiedza chemagetsi. Bhatiri isimba rakasiyana-siyana uye rinowanzoshandiswa, rakakodzera kushandiswa munzvimbo dzakawanda, asi simba rayo harina magumo, uye kana rabudiswa rinofanira kuraswa kana kuti kuzadzwazve. Nokuda kwezvinodikanwa zvikuru zvemagetsi, simba remagetsi rinofanira kubudiswa ndokupfuudzwa nguva dzose pamusoro pemitsetse inotungamirira.  Mubvunzo: Chii chakagadzirwa muzana remakore rechi18 chakaita kuti magetsi awedzere kuwanika?
