Back of Kindle is magnetic?

Its the speaker. Pretty much any speaker has a magnet inside.

Wikipedia: "The most common type of driver, commonly called a dynamic loudspeaker, uses a lightweight diaphragm, or cone, connected to a rigid basket, or frame, via a flexible suspension that constrains a coil of fine tinsel wire to move axially through a cylindrical magnetic gap. When an electrical signal is applied to the voice coil, a magnetic field is created by the electric current in the voice coil, making it a variable electromagnet. The coil and the driver's magnetic system interact, generating a mechanical force that causes the coil (and thus, the attached cone) to move back and forth, thereby reproducing sound under the control of the applied electrical signal coming from the amplifier."

I know the speakers have magnets, not sure about the rest of the back. :)

If you have a DS, put a paperclip on the back where the speakers are. Same happens with most other speakers!
