I understand that for AC clamp meters, a changing magnetic field induces a voltage/current in a wire loop and therefore it is possible to measure AC currents by induction. But how does a DC clamp meter work? In essence a DC current means a static magnetic field, and by Faraday's Law, no voltage/current is induced.
