Transported upon sled, somehow fitting every other bit of globe in (10)

I believe the answer is:

spellbound

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

'transported' is the definition.
(both can mean fascinated or enraptured)

I cannot understand how the rest of the clue works.

Can you help me to learn more?

(Other definitions for spellbound that I've seen before include "Captivated" , "Entranced" , "Held rapt" , "Enraptured" , "Transfixed, mesmerised" .)
