That magnetic field is responsible for the property of magnets to attract or repel other magnets and pull objects that are ferromagnetic like iron. Electrons are the reason behind the production of magnetic fields and magnetism. In permanent magnets spinning of electrons creates the magnetism.

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.|
