What is hall effect hall voltage?

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 a magnetic field perpendicular to the current. It was discovered by Edwin Hall in 1879


How can you find more information about the Hall effect?

The Hall effect was discovered by Edwin Hall, and references the difference in electrical current when exposed to a magnetic field. One can find out more about the Hall effect by consulting a physics textbook or physics teacher or professor.


Where you can implement hall effect in daily life?

Hall effect devices are useful for sensing and measurement: electrical current, electrical power (with separate voltage measurement), magnetic field, movement, and position.


What is hall effect sensor?

A Hall Effect sensor is a transducer that varies its output voltage in response to a magnetic field.In its simplest form, the sensor operates as an analog transducer, directly returning a voltage. Hall Effect Sensors consist basically of a thin piece of rectangular p-type semiconductor material such as gallium arsenide (GaAs). When the device is placed within a magnetic field, the magnetic flux lines exert a force on the semiconductor material which deflects the charge carriers, electrons and holes, to either side of the semiconductor slab. This movement of charge carriers is a result of the magnetic force they experience passing through the semiconductor material. As these electrons and holes move side wards a potential difference is produced between the two sides of the semiconductor material by the build-up of these charge carriers. The effect of generating a measurable voltage by using a magnetic field is called the Hall Effect. Hall Effect sensors and switches are designed to be in the "OFF" when there is no magnetic field present. They only turn "ON", when subjected to a magnetic field of sufficient strength and polarity.There are two basic types of digital Hall Effect sensor, Bipolar and Unipolar. Bipolar sensors require a positive magnetic field (South Pole) to operate them and a negative field (North Pole) to release them while unipolar sensors require only a single magnetic south pole to both operate and release them as they move in and out of the magnetic field. Here we are using a unipolar sensor

Why hall voltage increases with increase in magnetic field?

Since eEH= e(V X B) As magnetic field increases the lorentz force acting on the carriers increases which in turn increases the hall field associated with the carriers and hence hall voltage increases as magnetic field is increased.


What is hall effect?

If a semiconductor carrying a current ( I ) is placed in a transverse magnetic field ( B ), an electric field ( E ) is induced in the direction perpendicular to both I & B.This is called hall effect.for full explanation visit http://www.ecematerials.com/2013/07/hall-effect.html


Hall effect in electronics and communication?

When a current carrying conductor placed in magnetic field than a voltage across the surface is arise this voltage is known as hall voltage and this phenomenon is know as hall effect. It is useful for consider whether the applied material is PNP or NPN


What is Hall effect and what is a Hall effect current transformer?

a current flow close to a magnetic source it influence the sources hall effect is a disturbed signal as a function of speed.
