Why Is Iron Magnetic and Wood Not?

Each atom of iron has an unpaired electron whose spin can be lined up to that of the unpaired electron from a neighboring iron atom. The spinning of the charged electron creates a magnetic moment which in turn can align with an external magnet thus making iron magnetic. Atoms of wood do not have unpaired electron spins that can line up with a magnet and so it is non-magnetic.
