마이크에서는 소리, 즉 공기의 떨림이 마이크에 도달하면 그 떨림에 맞추어 마이크의 진동판(Diaphragm)이 떨리게 된다. 이로 인해 진동판에 연결된 코일이 같이 떨리게 된다. 그리고 전자기 유도의 원리에 의해 이 떨림에 맞는 전류가 발생한다. 코일이 움직이는 원리로 작동하기 때문에 코일 이동형 마이크(Moving Coil Microphone)라고 하기도 한다.
다이내믹 마이크는 외부 전력이 필요 없으며, 다른 마이크에 비해 온도 변화나 외부의 충격에 강하다. 따라서 널리 사용되며, 우리가 일반적으로 접하는 마이크는 대부분 다이내믹 마이크다. 원리상 자석을 이용하기 때문에 외부에 강한 자기장이 있으면 영향을 받는다.

가장 많이 사용되는 형태인 저주파 방식은 금속 탐지기 내부의 수신·발신 코일과 외부 금속 간의 전자기유도와 맴돌이전류를 통해 금속의 존재를 확인하는 것이다. 발신 코일에 전류가 흐르면 자기장이 형성되는데, 외부에 금속이 감지되면 발신 코일 자기장에 의한 맴돌이전류가 발생하여 또 다른 자기장을 만들어낸다. 이것이 수신 코일을 지나면, 전자기유도에 의해 코일에는 자기장의 변화에 반대방향으로 기전력이 발생하여 전류가 흐르게 되고, 회로에 흐르는 전류를 통해 금속의 존재 여부를 알 수 있게 된다]]> 2021-06-03 07:26:39 UTC https://padlet.com/newsong/z8husigw51o5cakg/wish/1581887224 고은석 https://padlet.com/newsong/z8husigw51o5cakg/wish/1581887691 2021-06-03 07:26:55 UTC https://padlet.com/newsong/z8husigw51o5cakg/wish/1581887691 소준성 https://padlet.com/newsong/z8husigw51o5cakg/wish/1581888132 2021-06-03 07:27:10 UTC https://padlet.com/newsong/z8husigw51o5cakg/wish/1581888132 https://padlet.com/newsong/z8husigw51o5cakg/wish/1581888492 20816 이영채
