Will it stop the servo from working properly? It would be a medium to strong magnet and the servo is a small one.
Why not simply try it?
It might damage it (?). And I haven't got the servo (yet).
Can I stick a magnet on a servo?
Yes.
Will it stop the servo from working properly?
No.

The only magnetic part in the servo is the motor. It is pretty unlikely that any magnet you could mount on (the shaft of) a servo of a given size, would in any way influence the motor.
Just keep your magnets away from your floppy disks.

And your credit cards, and your CRT shadow mask.

Not so relevant nowadays.

What do you use a CRT for?
Actually, I mean I want to glue a magnet on the actual motor, not the shaft.

A lot of POS systems in the UK use chip & pin but I think some cash point machines still read the magnetic strip.
It seems the USA is lagging behind with C&P.

Television studio's
We have nearly phased out all our CRT video monitors but probably still have 20+ left to go. Broadcast quality LCD video monitors are not cheap so we tend to replace with them as the CRT's break beyond repair (usually tubes as they are hard to come by now)
We were, ok I was talking about servos...

You really need to explain that - including the reasons why - in more detail.
Attaching a very powerful magnet - comparable to the field magnet - to the shell of a motor may affect its operation. Attaching it to a more distant part of the servo casing is much less likely to matter.
I thought I would have a little fun with Riva. 
If you want to stick a magnet directly to the servo's motor, maybe consider Velcro instead.
Hi,
We need more info on your application, why a magnet on the actual motor itself? or the side of the case of the servo?

Sorry if I wasn't clear. I want to put a magnet on a servo (with glue or so) so that I can place it on metal surfaces and remove it again (see picture)
So... Would that what I described work?
the electromotor in the servo has a magnet as stator so it should be no problem, so the rotation of the magnet is only important, to keep the motor running.
