When they break, the broken pieces are of the same polarity as the
original magnet.  Therefore they come together at the break north to
south.  All you got to do is test fit them to make sure you got the right
pieces if there aremore than one, tale em apart again, clean everything
good with solvent, let it dry, then  butter em up with JB,  and put em
back in the same order.   Let it set for a couple days to be sure the
epoxy  is at max strength.  As to the magnetic field strength, it may be
a trifle less but it don't seem to make a difference.  The repair lasts
if done right (the cleaning first is the key to all epoxy repairs. You
don't want even  fingerprint on the surfaces to be glued).
    I know a couple of retired GE dealers - and both of em epoxied  a lot
of magnets.  So we can assume that some of our deck motors have been
repaired this way.
