WebHow the Hall Effect clamp meters work. As current flows through a conductor being measured, the iron core formed by the jaws of a Hall Effect clamp meter allows the magnetic field to easily pass through—more easily, in fact, than air. When the magnetic field (flux) comes to that small air gap in the tips of the jaw, the field must jump that gap.
