Your physics is backwards here. The conductive casing of the hard drive will tend to reject magnetic fields inside. More precisely, the current you induce will produce a field in the opposite direction from the one you're applying, and the superposition of the two will result in a net smaller magnetic field inside the drive. That is, unless you can find a hard drive whose casing has a negative resistance. :-) See, for example, Zahn's "Electromagnetic Field Theory: A Problem Solving Approach." -- Riad Wahby [EMAIL PROTECTED] MIT VI-2 M.Eng _______________________________________________ Full-Disclosure - We believe in it.
