What is the DC clamp meter measuring principle

What is the DC clamp meter measuring principle

Answer:

Alternating current magnetic field can obtain the induced voltage as long as the coil is used, and the fixed magnetic field produced by the DC must be obtained with a magnetic sensor (Holzer component).
Since there is a magnetic field around the current and is proportional to the magnitude of the current, it is possible to know the magnitude of the current as long as the magnetic field is detected.
