A minor drawback of this probe is that it may require zero adjustment. References [2-3] also contain good descriptions and should be consulted especially for the analysis. Vary the sample current from zero up to its maximum value in equal intervals. Notice how the program pauses at each step of current and takes the specified number of measurements at that amount of amps. The Hall effect essentially is due to the Lorentz force F acting on each electric charge q moving with velocity v in a magnetic field B. This potential developed is Hall voltage & the phenomenon is called Hall effect. We are engaged in manufacturing & supplying a wide range of Hall Effect Experimental Setup.

After the program has ran it’s test, save the file to a location in the computer. The Hall voltage is caused by the deflection of the moving charge carriers in the magnetic field due to the Lorentz force, of which, direction can be predicted by the right hand rule. The Hall effect was first observed by an American scientist, E.H.Hall, in 1879. The Hall Effect experiment (conducted by Edwin Hall in 1879) determines the sign of the charge carriers in current flow.
