An attractive device in current production (13)

I believe the answer is:

electromagnet

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

'an attractive device' is the definition.
'electromagnet' can be an answer for 'device' (electromagnet is a kind of device). I am not certain of the 'an attractive' bit.

I don't understand the remainder of the clue.

Can you help me to learn more?

(Other definitions for electromagnet that I've seen before include "Device using current to attract iron" , "Powered attractor" , "Device attracting items when a current is passed through it" , "attractive item" .)

I've seen this clue in The Irish Independent and The Irish News.
