  • Page 8: Brief Introduction

    Gaussmeter IGM11 Operating Instructions MAGSYS systeme Chapter 2 Brief Introduction 2 Brief Introduction Measurements with the gaussmeter utilize the Hall effect as principle of measurement. A Hall sensor is a symmetric current-carrying semiconductor. A magnetic field running perpendicular through this element generates an asymmetry on the chip and thereby creates an output voltage which, at first approximation, is proportional to the product of magnetic field strength and forced current.
