Use a bulk eraser on them, then try again.  A bulk eraser is actually just
a strong magnet.  The one I have looks like this from one end:

            ___________
           | --------  |  Steel case with steel plate

               ____
           | \|____|/  |  Bar magnet in \___/ shped steel plate to match
           |___________|  top plate and then steel case around all.

I expect that any stong magenet that covers the whole surface cold be used.
