Duba wurin da ke ƙasa sannan ka amsa tambayar daga baya a cikin harshe ɗaya kamar yadda wurin yake:  Passage: Rashin filin magnetic na ciki a Venus ya kasance abin mamaki, saboda yana da kama da Duniya a girmansa kuma ana sa ran zai ƙunshi dynamo a cikin zuciyarsa. Dynamo yana buƙatar abubuwa uku: ruwa mai gudanarwa, juyawa, da haɗuwa. Ana tunanin cewa tsakiya tana da wutar lantarki kuma, kodayake ana tunanin juyawa yana da jinkiri sosai, kwaikwayon ya nuna cewa ya isa ya samar da dynamo. Wannan yana nuna cewa dynamo ya ɓace saboda rashin haɗuwa a cikin zuciyar Venus. A duniya, haɗuwa yana faruwa a cikin ruwa na waje na tsakiya saboda kasan ruwa na ruwa ya fi zafi fiye da saman. A kan Venus, wani taron sake farfadowa na duniya na iya rufe tectonics na tectonics kuma ya haifar da rage yawan zafin jiki ta hanyar fata. Wannan ya haifar da yanayin zafin jiki ya ƙaru, ta haka ne ya rage yawan zafin jiki daga ainihin. A sakamakon haka, babu wani geodynamo na ciki don fitar da filin maganadisu.
