What is Moving Coil Microphone? Working, Diagram, & Applications

NettetMagnet moving toward the coil: Some voltage measured, rising to a peak as the magnet nears the center of the coil. Magnet passes through the middle of the coil: Measured voltage rapidly changes sign. Magnet passes out and away from the coil: Voltage measured in the opposite direction to the earlier case of the magnet moving into the coil.

NettetA north pole of a magnet is moved towards the coil before coming to rest inside it. The needle of the ammeter initially deflects to the right. What happens next? NettetWhen one end of a bar magnet is pushed into the coil, the ammeter pointer deflects. This is because: • the movement of the bar magnet causes an induced potential difference in the coil • the induced potential difference causes a current, because the coil is part of a complete circuit.
