Subject: Coil + magnet sensors = long period noise?

In a recent post, Chris Chapman commented "Coil + magnet systems detect 
velocity and are likely to suffer noise problems at very long periods".

Could you elaborate a little on this?  What is the source of the noise, 
and what sort of periods are we talking about?
