Polarity matters a great deal. Electromagnets can and do repel. It all depends on the direction of the current flow in the wire (which is why polarity matters). Try touching the wires from a speaker to a AA battery. Hook it up one way and the cone moves out. Reverse the polarity and the cone will move in.
