  • Page 7: Brief Introduction

    Industrial Gaussmeter IGM11 Operating Instructions Chapter 2 Brief Introduction Brief Introduction Measurements with the gaussmeter utilize the Hall effect as principle of measure- ment. 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.

    Gaussmeter IGM11 Operating Instructions Chapter 3 Function of the Gaussmeter Function of the Gaussmeter The Hall Effect 3.1.1 Linear Properties of the Hall Probe The measurement is based on the deflection of charge carriers in a magnetic field inside a conductor. Thus, the basis of the measurement of the magnetic flux density is the Lorentz force.
