Charm died out when dissipated (9)

I believe the answer is:

dispelled

'dissipated' is the definition.
('dispel' can be a synonym of 'dissipate')

'charm died out' is the wordplay.
'charm' becomes 'spell' (both can mean a bit of magic).
'out' is an insertion indicator.
'spell' put inside 'died' is 'DISPELLED'.

'when' acts as a link.

(Another definition for dispelled that I've seen is " Piled sled (anag.)".)

I've seen this clue in The Globe and Mail.
