Magnetic field microphone
WebMagnetic force microscopy is primarily used to scan the magnetic field of a sample. Once the first scan involving contact has been done, the second scan (non-contact) is dependent on the magnetic force between the tip … Web18 aug. 2013 · The Microphone, also called a “mic”, is a sound transducer that can be classed as a “sound sensor”. This is because it produces an electrical analogue output signal which is proportional to the “acoustic” sound wave acting upon its flexible diaphragm. This signal is an “electrical image” representing the characteristics of the acoustic …
