When a fluctuating electric current flows through the coil (orange), it becomes a temporary electromagnet, attracted and repelled by the permanent magnet (blue/red).
In order to translate an electricalsignal into an audible sound, speakers contain an electromagnet: a metal coil which creates a magnetic field when an electric current flows through it. ... A microphone uses the same mechanism as a speaker in reverse to convert sound into an electrical signal.
