Unlike the electric filed , the magnetic field is not fundamental, That is, the concept of a magnetic force is not a separate force, but arises directly from the electric force, if the principles of Einstein's special relativity theory are applied to the electric force.The magnetic force can cause two parallel wires to attract if they are both carrying an electric current (that is, a flow of electrons). This is in spite of the fact that wires are usually electrically neutral, so that no direct electric repulsion (or attraction) usually occurs between the wires.
Hope this helps.
