[kung fu 11]

السلام عليكم و رحمة الله و بركاته
كنت اقراء احد الكتب فوجدت تلك العبارة

You’ll now have to find something cylindrical
with a diameter of near enough 140mm (5-1/2in).
A coil will then have to be made of 40 turns of 32
s.w.g. enamelled copper wire. The wire should be
wound close together and kept well bunched and
taped to keep it together when removed from the
former. Two such coils are required, both are
identical.

ما معنى كلمة s.w.g. فى هذه الجملة
اريد ان احدد نوع السلك او طول الملف او قطر السلك .... إلخ
ماهى الـ 32
اى معلومات تفيد فى عمل الملف ضرورى يا اخوة
