What sort of toroids? If they're powdered iron, it should be no
problem. If they are relatively low mu ferrite, it should be a minor
problem at worst if you keep the glue line thin. If they are mu=6000
toroids, then a thousandth of an inch gap in an inch long path is
quite significant. If you relieved stresses, the break may not fit
back together with "zero" gap; it's something to check. A gap isn't
necessarily bad, just something to consider. In fact, gapped cores
can store more energy than ungapped.

Cheers,

I recently bought several toroids, and unfortunately, one of them
dropped and broke in half.

Is it possible to super glue the thing back together? It's a clean break.

I was figuring that since toroid coils are often stacked, it would be
similar in effect.
