[0:00]Ever wondered how a speaker's magnet and coil work together to produce sound? A typical speaker uses a coil of wire in close proximity to a fixed magnet. The magnet's magnetic field stays the same, but when you send an electric current through the coil of wire, a magnetic field forms around the wire as well. And this field is constantly changing with the audio signal coming from the amplifier. The two magnetic fields interact, and because the magnet is fixed, this causes the very lightweight coil of wire to move along with those interactions.
