How is momentum conserved when a magnet attracts a metal?

How is momentum conserved when a magnet attracts a metal?

Suppose your have any magnetic object and no external force acts upon it,
and the object comes near a metal which causes an impulse (think that will
happen). However, the magnetic force is internal to the object, and
momentum should be conserved, so where have I gotten it wrong?
