A ferrite is a brittle thing, no give at all.
Unforgiving yet uncomplaining.
Knocked a ac surge arrestor off the desk like I was a cat or summin and ofc it dropped precisely atop a ferrite core that formerly enclosed a coax cable to reduce rfi. Shattered into a million shards. Spose some use can be made of it somehow.
Take care of your ferrites, for they are very sensitive.
