Hall effect equation
http://physics.bu.edu/~duffy/semester2/d12_halleffect.html WebThis is called the Hall Voltage, VH. The positive and negative charges drift to opposite ends of the conductor producing a hall voltage when a magnetic field is applied. An equation for the Hall voltage VH is derived from the electric and magnetic forces on the charges. The electric and magnetic forces on the electrons are equal and opposite.
