A good way to clean stuff off a magnet pole is adhesive tape.

 
If the surface is too convoluted for the tape to work, there is a
product in the UK called "Copydex", which is sold as a carpet glue but
can be used to remove debris from a magnet.  It is an emulsified latex
solution which doesn't stick well to metal surfaces and can be peeled
off easily.
 
You apply the Copydex thickly over the surface to be cleaned - and then
wait.  Eventually the milky white liquid dries to complete transparency,
then it is strong enough to be peeled off, bringing the debris with it.

 
I would imagine any of the "silicone caulks" would work
equally well.

It needs to peel off easily.  The silicone caulk I have used has always
stuck very firmly to metal.

The downside with any of these is that there is a
"drying time".  I don't imagine the folks using
this bit of kit would sit around waiting before
reusing (or retiring) it.  <frown>  Imagine having
to similarly clean a 'scope probe between uses...

Yes, this is very much a specialist tool for getting metal debris out of
magnet gaps in moving coil meter movements or disc cutterheads, where
time is not a major factor.
