Expression for hall voltage
WebThe first term is the same as before and describes the electric field parallel to the current. The second term describes an electric field perpendicular to the current. In other words, if we send a current through a sample and apply a magnetic field, a voltage develops in the direction perpendicular to the current—this is called the Hall effect.The voltage is called … WebNov 5, 2024 · The expression for magnetic force on current can be found by summing the magnetic force on each of the many individual charges that comprise the current. Since they all run in the same direction, the forces can be added. Right Hand Rule: Used to determine direction of magnetic force. ... (called the Hall voltage) is produced across an ...
