Hall voltage states that if a metal or a semiconductor carrying a current I which is placed in transverse magnetic field B, an electric field is induced in a direction perpendicular to both I and B. And is denoted by Vh. Hall Voltage is usually measured using the Volt for Electric Potential. Note that the value of Hall Voltage is always negative. Typically, the value of Hall Voltage lies in the range from -10000 to 10000.
