What it means
میدان مغناطیسی (meydân-e moghnâtisi) is the standard Persian term for magnetic field, the region of space around a magnet or electric current where magnetic forces can be detected. The compound has a mixed etymology. میدان (meydân) comes into Persian via Arabic مَيْدَان (maydân), which is itself an Iranian borrowing that traveled from Proto-Iranian into Arabic and back, meaning field or arena, a space in which something acts. مغناطیس (moghnâtis) is a Greek loanword, from the region of Magnesia in Asia Minor where lodestones were found in antiquity; it entered Persian through Arabic scientific texts. The adjective مغناطیسی (moghnâtisi) means “magnetic.” There is no competing native Persian equivalent: this term is universal in Iranian physics education from secondary school onward.
How to use it
- زمین یه میدان مغناطیسی قوی داره. (zamin ye meydân-e moghnâtisi-ye qavi dâre.) “The Earth has a strong magnetic field.”
- میدان مغناطیسی آهنربا رو رسم کنید. (meydân-e moghnâtisi-ye âhanrobâ ro resm konid.) “Draw the magnetic field of the magnet.”
- تغییرات میدان مغناطیسی میتونه قطبنما رو منحرف کنه. (taghirât-e meydân-e moghnâtisi mi-tune qotbnomâ ro monharef kone.) “Changes in the magnetic field can deflect a compass.”
- میدان مغناطیسی خورشید خیلی پیچیدهست. (meydân-e moghnâtisi-ye khorshid kheyli pichide-st.) “The Sun’s magnetic field is very complex.”
Cultural note
The word مغناطیس entered Persian through the great tradition of Arabic-language science that Persian scholars like Ibn Sina and al-Biruni both contributed to and inherited. These scholars transmitted Greek knowledge of magnetism, including the name Magnesia, into the Islamic scientific corpus, from which it passed into Persian educational vocabulary. Today میدان مغناطیسی appears in Iranian national university entrance exams (کنکور, konkur) as a core physics term, and the solar magnetic field is a topic of active research at Iranian universities, particularly in connection with space weather and satellite operations.
