Can you record "sound" through a microphone silently, through inductance?

By which I mean recognizeable audio. If, for example, you were to take a stereo, and dismantle the speaker, so that only the speaker coil was left, would the coil in a microphone still pick up whatever the stereo was playing? I get that decent dynamic mic is pretty well shielded, but what about a cheap condenser mic like in a dictaphone? I don't think those have coils though, but would it work if the "speaker" were relatively close?

    Yes, that is effectively an audio transformer.

    Sorry, having trouble interpreting the question.

    "Can you record "sound" through a microphone silently, through inductance?" NO, no sound, there is no sound to record.

    next question: there needs to be a coil that moves in a magnetic field to generate a voltage. A speaker can be used as a microphone, but you need the magnet and the coil has to be suspended so it can move, vibrate.  A coil by itself will do nothing.

    different interpretation to question:

    You seem to be asking if a microphone coil will pick up sound from a dismantled speaker. No, a dismantled speaker will produce no sound.

    lat question, don't understand. Certainly a cheap condenser microphone will work. Yes, they have no coils.
