the magnet is doing its best not to come apart in one piece.
They used the *good* resin, as well as way too much glass fiber reinforcement.
At least too much to be any fun when taking it apart again.
I took some SEM shots of the wire, and you can kinda see how it's NbTi embedded in a copper matrix, but to be honest, I was hoping for way more contrast with the SE detector.
BSE is broken, and EDX is in the works...
Maybe @breakingtaps has any tipps?
