Key Stage 3
Meaning
A picture of a microphone.
A microphone is an electrical device that turns the vibration of a sound into an electrical signal.
About Microphones
- Sound transfers information which a microphone converts into an electrical signal.
- Microphones use a coil of wire and a permanent magnet to turn a vibration into an electrical signal.
- When the receiver vibrates the coil of wire moves around the permanent magnet to make a current in the coil of wire.

Key Stage 4
Meaning
A picture of a microphone.
A microphone is an electrical device that turns the vibration of a sound into an electrical signal using the generator effect.
About Microphones
- Sound transfers information which a microphone converts into an electrical signal.
- Microphones use a coil of wire and a permanent magnet to induce a current in the coil when receiver vibrates.
- When the receiver vibrates the coil of wire moves around the permanent magnet to make a current in the coil of wire.
