[Lowfer] Repairing Ferrites

[ED]

If you keep the  glue joint very very thin it won't have much effect.  
For high permeability cores there might be a small loss in inductance.  
I use epoxy and heat the pieces before joining to make the adhesive much 
thinner and easier to squeeze out of the gap.
