Genuine point identified without magnetism (4,5)
I believe the answer is:
true north
'identified without magnetism' is the definition.
I can't judge whether this definition defines the answer.
'genuine point' is the wordplay.
'genuine' becomes 'true' (associated in meaning).
'point' becomes 'north' (north is a kind of point).
'true'+'north'='TRUE NORTH'
Can you help me to learn more?
(Other definitions for true north that I've seen before include "Position of maximum latitude" , "Pole" , "rarely needled when on the move" , "Direction aligned with earth's axis" , "In the direction of one of the poles" .)
