Publication to acquire something attractive? (6)

I believe the answer is:

magnet

I'm a little stuck... Click here to teach me more about this clue!

'something attractive?' is the definition.
(I've seen this before)

'publication to acquire' is the wordplay.
'publication' becomes 'mag' (abbreviation for magazine).
'to acquire' becomes 'net' (I can't explain this - if you can you should believe this answer much more).
'mag'+'net'='MAGNET'

Can you help me to learn more?

(Other definitions for magnet that I've seen before include "Attractive item" , "drawer?" , "Powerful attractor" , "Old comic" , "One that attracts" .)

I've seen this clue in The Times.
