Whenever electric charge moves there will be an associated magnetic field. This is a relativistic effect Either the charge can move by you, or you can move by the charge. In both cases, a magnetic field will be produced.

The charges can be confined to a wire of be flying freely in space. An external magnetic field can push or pull on the charges. This is how the electron beam is deflected in the picture tube of your TV set. A motor uses external magnets (or electromagnets) to push on the charge carrying wires of the armature (spinning part.)
