Thus they are very common. The purpose of this effect is to study the behavior of the current carried in the respective conductors present in the circuits. In this lesson, you will learn about two types of magnetic sensors: Hall effect sensors and reed switches. voltage is the Hall voltage and is given by. Hall effect sensors are used for proximity switching, positioning, speed detection, and current sensing applications.. When this charged conductor comes in contact with the magnetic field which is in a perpendicular direction to the motion of electrons, the electrons get deflected. If the magnetic field is oriented perpendicular to the direction of the electron’s motion, the electron experiences a force that is perpendicular to both the direction of motion and the orientation of the magnetic field. Magnetic sensors convert magnetic or magnetically encoded information into electrical signals for processing by electronic circuits, and in the Sensors and Transducers tutorials we looked at inductive proximity sensors and the LDVT as well as solenoid and relay output actuators. The physical spacing of the Hall effect sensors is very impor-tant. Paper deals with hall effect sensors used for position measurement.
