Michael took Fay round the academy (7)
I believe the answer is:
faraday
'michael' is the definition.
(I know that michael can be written as Faraday)
'fay round the academy' is the wordplay.
'round' is an insertion indicator.
'the academy' becomes 'rada' (I can't explain this - if you can you should give a lot more credence to this answer).
'fay' placed around 'rada' is 'FARADAY'.
'took' is the link.
This may not be right. It may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for faraday that I've seen before include "English physicist and chemist, d. 1867" , "unit" , "Man of note" , "Michael -, nineteenth century English physicist and chemist" , "Scientist" .)
