Small periodical bags attractive bodies (7)
![Ross](/clue/static/ross-mug.min.png)
I believe the answer is:
magnets
'attractive bodies' is the definition.
The definition and answer can be both man-made objects as well as being plural nouns.
Perhaps you can see a link between them that I don't see?
'small periodical bags' is the wordplay.
'small periodical' becomes 'mag' (short for magazine; 'small' indicates a short form).
'bags' becomes 'nets' (I've seen this before).
'mag'+'nets'='MAGNETS'
Can you help me to learn more?
(Other definitions for magnets that I've seen before include "attractive types" , "Attractive devices" , "Gets man (anag.)" .)
