Seized rear abs sensor

[bren172]

As the title states, my rear passenger side abs sensor has snapped and seized in place. Has anyone got any tips for getting the remains out?
I'll stick a photo in to show what I mean

Id try and knock the guts out from the back if access.

If not disc off, hammer and screwdriver or drill. Its plastic so ten min job

remove as much of the fine copper mesh wires as you can then pull the magnetic core out. Once the magnetic core is out it should come out fairly easily.
