WebWhen a bar magnet is moved through the coiling, the voltage detector measures the voltage in the circuit. Through his experiment, he discovered that there are certain factors that influence this voltage production. They are: Number of Coils: The induced voltage is directly proportional to the number of turns/coils of the wire. WebSep 26, 2024 · the dynamic microphone. In the magneto-dynamic, commonly called dynamic, microphone, sound waves cause movement of a thin metallic diaphragm and an attached coil of wire. A magnet produces a magnetic field which surrounds the coil, and motion of the coil within this field causes current to flow.
