Any particular uses (electronic) for long ferrite beads? (toroids)?

Am aware of toroidal ferrite txformers used in Joule Thief apps,any other uses for the 'longer' ferrites ?

You could build yourself a core memory (look it up).

Oh yeah, need a lot of beads though...
My college Physics dep't had one but the whole machine was in bits.

Hah, hah! Pun intended, I presume...

You're welcome to the laugh, but I didn't intentionally say anything humourous.

We're discussing ferrite core memory, and you talked about the machine being "in bits" :-) I'm glad it was unintentional, or it'd be a pun worthy of Goodhart....

Oh crap, I get it now.
