Seismometers are tools which measure motion in the ground including seismic waves generated by earthquakes, volcanoes, and other activities which might create seismic waves. Seismometers measure any movement of seismic activity in the earth and today this is done by electronic means whereby the machine measures any changes in seismic activity in the surrounding areas of the seismometer.

The force generated by the aligned atoms creates a magnetic field.Magnets are important because of their properties A particle moving in a magnetic field feels a force proportional to his speed, and to the field, so you can use a magnet that produce a field in a certain way and shape, in order to catch a particle in motion.
