Additional field coils around motors

In a post I'm too lazy to search for right now Joe Johnson said something to the effect of "if you can pick up a large paperclip with a motor, chances are the motor could benefit from an external flux yoke" (I think that's what it is called) "Torque can be increased up to 20% in some cases"

And you'll notice the FP motor has one of these doo-dads and apparantly it serves a very important purpose.

So, I haven't tried it, and I haven't yet learned about magnetic flux and whatnot (I think about 3 weeks away from learning about that in Physics) but it sounds logical and I'd definitely be willing to try it. Does anyone know if you can pick up a paperclip with a CIM?
