Hall Effect is discovered and discussed the impact of the American physicist Edwin Hall is the
tendency for charge carriers, whether positive or negative for the shift towards the parties in
electrical conductors due to the magnetic field applied or Almtard him. The resulting voltage (the socalled Hall) between the electrodes Almtaxh effort in electrical conductor Qtabath rely on this carrier
.signal, this force, which skew the current derailed called the Lorentz force
If placing the conductor in a magnetic field perpendicular to the direction of the electric current, the
room electrically teams effort will be generated and the so-called hard Hall voltage generated and
given to the relationship teams:
Where B = magnetic field, I = electric current passing through the slide, d = thickness of Mosul, e =
electron charge, n = density of free shipments.
The amount:
Called Hall depends on both the temperature and the type of Mosul coefficient does not depend on
the dimensions of the slide, and is determined by the type of cargo (electrons or positive holes) in
accordance with the current direction and the direction of Hall effort arises Hall effort as a result of
deviation free shipments impact of the external magnetic field as determined by the direction by the
left hand Base Fleming.
In 1988 the world was derived von Klinsng (K. von Klitzing) what is known today as the
phenomenon or Quantum Hall effect .
