Which property does a Hall-Effect clamp rely on when measuring current flow in a circuit?

A Hall-Effect clamp utilizes the principle of magnetism to measure current flow in a circuit. The Hall effect occurs when an electric current passes through a conductor placed within a magnetic field. This interaction generates a voltage that is perpendicular to both the current and the magnetic field. In the context of a Hall-Effect clamp, the clamp itself contains a Hall sensor that detects the magnetic field generated by the flowing current. By measuring this induced voltage, the clamp can accurately determine the level of current flowing through the conductor.

The other properties listed, such as electricity, resistance, and inductance, do not directly apply to the working principle of a Hall-Effect clamp in the context of current measurement. While electricity is a fundamental component of the process, it is the magnetic property that provides the necessary information to measure current effectively.
