Hall effect error analysis and what method is used in the Hall experiment

, the excitation current and Hall current time is too long, resulting in heating, affecting the test results, <WBR> so that the results are biased Hall effect is when a solid conductor has a current through it, and is placed in a magnetic field, the charge carriers within the conductor are subject to the Lorentz force and biased to one side, followed by the generation of a voltage, in addition to the conductor, semiconductors can also produce the Hall effect, and semiconductors have a stronger Hall effect than the conductors. The electric field force balances the Lorentz force. Explained in the conductor on the external perpendicular to the current direction of the magnetic field, will make the wire in the electrons and holes by the different directions of the Lorentz force and gathered in different directions, in the gathering up of the electrons and holes in the electrons and holes in the electric field between the electric field, this electric field will make the subsequent electron hole by the power of electricity to balance off the magnetic field caused by the Lorentz force, so that the subsequent electron holes can be successfully passed through the electronic hole will not be deflected, which is known as the Hall effect. The built-in voltage is called Hall voltage.
