This means that when a drop of liquid is mixed with a suitable solution of paramagnetic ions, which become magnetic in the presence of a permanent magnet, it will be pushed to where the field is weakest, and stay there.

ECONOMIST: Monitor

Wander into any eighth-grade science fair and you're likely to see an example of this destructive process at work - place two dissimilar metals in an electrolyte solution and one of the materials will slowly steal ions from the other, causing it to oxidize, become brittle and eventually break apart.
