Explain how the atoms of a piece of wood are tiny magnets, yet the piece of wood is not.

The electron in atoms spin, and have magnetic moments. The electrons also have an orbital magnetic moment. However, when all the moments from the atoms are added up, it results in a net zero magnetic moment. All of the small ones cancel each other.
