Excellent point, and one that is frequently overlooked in these
legends....

Actually, it would shield *by* concentrating them.  The magnetic lines
would tend to flow through the steel, rather than through the air
above it.

Bottom line, however, is that, unless the motor was very poorly
shielded (plastic casing?) and very inefficient (magnetic fields *not*
concentrated within the motor to do work turning it) and very close to
the bottom of a very thin wood desk, with tapes sitting right at the
very bottom of the drawer..... Let's just say that this is unlikely.
