What has metal core working with good capture? (13)
I believe the answer is:
electromagnet
'what has' is the definition.
I can't tell whether this definition defines the answer.
'metal core working with good capture?' is the wordplay.
'working with' indicates an anagram (working with the letters).
'good' becomes 'g' (abbreviation).
'capture?' becomes 'net' (I've seen this before).
'metal'+'core'='metalcore'
'metalcore' with letters rearranged gives 'electroma'.
'electroma'+'g'+'net'='ELECTROMAGNET'
Can you help me to learn more?
(Other definitions for electromagnet that I've seen before include "Device using current to attract iron" , "Device attracting items when a current is passed through it" , "Powered attractor" , "attractive item" .)
