A moving coil microphone functions on the basic principle of Electromagnetic induction. It has a copper wire coil, which when moves in the magnetic field a voltage is generated. Then it is induced in the coil in proportion to its amplitude of vibration, which, in turn, depends on the sound pressure. A moving coil microphone [...]
