Tycoon the attractive sort we hear (7)

I believe the answer is:

magnate

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

'tycoon' is the definition.
(I know that tycoon can be written as magnate)

I don't understand the remainder of the clue.

Can you help me to learn more?

(Other definitions for magnate that I've seen before include "Baron" , "Fat cat" , "Tycoon" , "Fellow with a lot of money" , "Wealthy business leader" .)

I've seen this clue in The Sun.
