There is eHow: Why Do Magnets Destroy Computers?
My general opinion has been that strong magnets (not your average refrigerator magnets) and microwaves (probably not your normal mobile phones) can damage data on magnetic storage.
But, I'd like to invite Gravitas who described worries on static charges a short while back here for a second opinion.
What every elementary school computer teacher would say is to keep magnets away from the computer. They're basically afraid that the magnet will start flipping the bits on the magnetic hard drive.
As nik said earlier, the magnets aren't strong enough to do any damage. I would stay on the safe side though and err on the side of keeping magnets away from the computer anyway.
