Hall effect

Discover the foundational principle of magnetic field influence on electrical currents through the Hall Effect. This concept, articulated by Edwin Hall in 1879, outlines the generation of a potential difference across an electrical conductor when subjected to a magnetic field perpendicular to the current flow. Our comprehensive mind map delves into the theoretical underpinnings, including the Hall voltage formula and the influential factors, such as carrier density and current. Additionally, it highlights practical applications spanning from semiconductor physics to the automotive industry, demonstrating the effect's versatility in magnetic sensors and beyond.

RELATED TERMS

HALL VOLTAGE The voltage generated across the conductor due to HALL EFFECT

HALL COEFICIENT The proportionality constant between the Hall voltage and magnetic field and current

When a current carrying conductor is placed in a magnetic field then a force is experienced by the conductor which is perpendicular to both the magnetic field and the direction of current , this phenomena is known as HALL EFFECT

APPLICATIONS AND USAGE

FORMULAES

HALL VOLTAGE (VH) The Hall voltage is the voltage difference measured across the width of the conductor due to hll effect it can be measured as VH=IB/ neA Where I = Current flow through the conductor B= Magnetic field strength n=no. of charge carrier e= charge T=thickness of the sensor

HALL COEFFIECIENT (RH) The Hall coeffiecient is a material-specific constantthat relates the hall voltage to the magnetic field and current. it can be determined using the formulae RH = VT/BI Where, B= Magnetic field strength I= Current flow through the conductor

PRINCIPAL

He was and American physicist, who discovered the eponymous HALL EFFECT He coducted thermoelectric research and also wrote numerous physics textbook.
