How seismograph works

1. Seismograph instruments are placed on the surface of the earth so, whenever the ground starts shaking the instrument's case moves.
2. There is a seismometer inside the seismograph so,only seismograph instruments case moves while seismometer remains still without any movement.
3. Seismograph instruments have a large powerful magnetic system for detection and case is wrapped with numerous coils of wire.
4. When an earthquake happens the case moves in relative the magnet move and generates an electric signals to the wire which further sent to the computer to create a seismogram.
