Choose Italian film about golf: it has drawing power (13)
I believe the answer is:
electromagnet
'it has drawing power' is the definition.
The definition suggests a singular noun which matches the answer.
'choose italian film about golf' is the wordplay.
I cannot quite understand how this works, but
'choose' could be 'elect' (electing is a kind of choosing) and 'elect' is found in the answer.
'film' could be 'et' (E.T. the Extra-Terrestrial) and 'et' is found within the answer.
'about' could be 'a' (abbreviation in Chambers) and 'a' is found in the answer.
'golf' could be 'g' (phonetic alphabet: alpha, bravo, charlie etc.) and 'g' is found within the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for electromagnet that I've seen before include "Device using current to attract iron" , "attractive item" , "Powered attractor" , "Device attracting items when a current is passed through it" .)
