The Hall effect is an extension of the Lorentz force, which describes the force exerted on a charged particle—such as an electron—moving through a magnetic field. This is the famous Quantum Hall Effect4. In its simplest form, the sensor operates as an analog transducer, directly returning a voltage. This will provide a useful background for our discussion of the quantum Hall e ect. similar setup - along with two bar magnets - are used to create the Hall effect and determine the . 2.04.7.2 Hall Effect 2.04.7.2.1 Anomalous 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. A four lead cable is attached so that the necessary electrical circuit can be used to detect the Hall voltage. Fig : A wheel containing two magnets passing by a Hall effect sensor.

For the sensing of magnetic field is used a module of Hall Effect KY-024 (see the Figure 6), which has a sensor of linear Hall Effect SS49E. The Hall effect probe is a thin slab of indium arsenide, InAs, cemented to a piece of fiberglass. The probe is equipped with a bakelite handle that is used to hold the probe in place. Gaj, in Comprehensive Semiconductor Science and Technology, 2011. The two Hall effect field probes, X 1 and X 2, are subjected to a common magnetic field of flux density B, produced in a magnetic circuit linked by alternating current I which flows in an impedance Z. Tripathi,Prof. During that time… In 1879 he discovered that when a conductor or semiconductor with current flowing in one direction was introduced perpendicular to a magnetic field a voltage could be measured at right angles to the current path. These electrical signals are then further processed by a user specific electronic circuit to give the desired output.Now days, these Magnetic sensors are capable in responding for a wide range of magnetic fields.
