http://iris.edu/hq/sis/resources/seismometers A simple seismometer, sensitive to up-down motions of the Earth, is like a weight hanging from a spring, both suspended from a frame that moves along with any motion detected. The relative motion between the weight (called the mass) and the frame provides a measurement of the vertical ground motion. A … See more The word derives from the Greek σεισμός, seismós, a shaking or quake, from the verb σείω, seíō, to shake; and μέτρον, métron, to measure, and was coined by David Milne-Home in 1841, to describe an instrument designed by Scottish … See more The first seismometer was made in China during the 2nd century.

WebMar 5, 2024 · 10.9: The Transformer. A transformer is a static electrical device that transfers electrical energy between two or more circuits through electromagnetic induction. A varying current in one coil of the transformer produces a varying magnetic field, which in turn induces a varying EMF or "voltage" in a second coil. http://ed-thelen.org/Seismo/Building_a_simple_seismometer.pdf
WebA seismometer comprises a pendulum (an inert mass) inside an airtight container that is attached by a hinge and a wire (for horizontal units) or a spring (for vertical units) to a supporting frame set firmly in the ground. One or more electric coils is attached to the pendulum and placed within the field of a magnet.
