Like coaches often, with a certain animal magnetism? (5-5)

'like coaches often' is the definition.
(I know that coaches are often horse-drawn)

'with a certain animal magnetism?' is the wordplay.
I cannot quite understand how this works, but
'with' could be 'w' (abbreviation) and 'w' is present in the answer.
'a' could be 'an' and 'an' is present in the leftover letters.
'animal' could be 'horse' (type of animal) and 'horse' is found within the answer.
This may be the basis of the clue (or it may be nonsense).

Can you help me to learn more?
