Fled away from weird magnetic field - it's quite mysterious (9)
I believe the answer is:
enigmatic
'mysterious' is the definition.
(I've seen this before)
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for enigmatic that I've seen before include "Like a puzzle" , "Ambiguous or puzzling" , "Mysterious or puzzling, like Mona Lisa's smile" , "Obscure, puzzling" , "Puzzling, like the Sphinx" .)
