Electrical resistivity is a basic measure of how well a material conducts electrical current. When a magnetic field is applied non-collinearly to the current direction the Lorentz force bends the trajectory of charge carriers and leads to a potential difference. This is known as the Hall effect named after Edwin Hall who discovered it in 1879.

· The Hall constant should not be confused with what researchers term the Hall resistance (often denoted by the same symbol used for the Hall constant). The normal resistance of the sample is just the voltage drop along the sample divided by I. In analogy the Hall resistance (in ohms) is defined as ΔVH /I — a kind of transverse resistance.
