aclinic line defined in 1939 yearaclinic line - Aclinic Line (Gr. a, not. klinein, to bend);
aclinic line - Line along which there is no dip of the magnetic needle. Elsewhere, owing to the magnetic attraction of the earth, freely suspended and horizontally balanced needles dip downwards at one end after having been magnetised. The aclinic line, also called the magnetic equator, makes an irregular curve roughly following the equator. Lines along which the magnetic dip is everywhere the same are called isoclinic lines.
