Answer 2

Seismograph is an instrument which is used to measure Earthquakes.

How seismograph works

• Seismograph instruments are placed on the surface of the earth so, whenever the ground starts shaking the instrument's case moves.
• There is a seismometer inside the seismograph so,only seismograph instruments case moves while seismometer remains still without any movement.
• Seismograph instruments have a large powerful magnetic system for detection and case is wrapped with numerous coils of wire.
• 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.
