Voice Coils

The voice coil component of a speaker is actually just an electromagnet. Electromagnets are coils of wire, and they’re normally wrapped around some kind of magnetic metal, like iron. By running an electrical current through the wire, you produce a magnetic field surrounding the coil; this field magnetizes the metal in the middle creating north and south polar orientations. The difference between an electromagnet and a permanent magnet is that you can switch the polar orientations on an electromagnet by reversing the current’s flow.
