DNEVNA PROMJENA JAKOSTI MAGNETSKOG POLJA ZEMLJE
Journal Title: UNKNOWN - Year 2000, Vol 12, Issue 1
Abstract
Dnevna promjena jakosti magnetskog polja Zemlje mijenja se prostorno i tijekom vremena. S obzirom na veliku preciznost novih protonskih magnetometara postavilo se pitanje kako se mijenja dnevna promjena udaljavanjem od baze. Zbog toga se radi usporedbe istovremeno mjerila dnevna promjena na bazi i na stajalištima koja su bila na raznim udaljenostima.
