All magnetic response functions of the MLX90251 are fully programmable for versatility and system tolerances reduction (End-of-Line Calibration). This e ect is known as the Hall e ect [1]. <> By Gary Pepka, Allegro MicroSystems, LLC . The Hall E ect 1 Introduction In 1879, E. H. Hall observed that when a current-carrying conductor is placed in a transverse magnetic eld, the Lorentz force on the moving charges produces a potential di erence perpendic-ular to both the magnetic eld and the electric current. Mainly Lorentz force is responsible for Hall effect . The Hall effect is the production of a voltage difference (the Hall voltage) across an electrical conductor, transverse to an electric current in the conductor and to an applied magnetic field perpendicular to the current. 5 Figure 1: The Hall effect for positive charge carriers. Magnetic sensors are solid state devices that are becoming more and more popular because they can be used in many different types of application such as s… Thus the Hall Effect Transducer is used. 7 0 obj The Hall Effect Principle has been named after an American physicist Edwin H. Hall (1855–1938). To explain Hall effect, consider a sample of a block of conductor of length l, width d and thickness t, through which electric current I is supplied along x-axis as shown in figure 1. Consider applying a voltage VL along the x-direction with an electric field Ex such that VL = LEx and a magnetic field B in the transverse z-direction. Advantages and Disadvantages. The south pole of the magnet goes towards the 'face' turning the device on. The electrons from different valleys moved in opposite directions across the sample, with one valley being overrepresented with respect to the other.
