WebHall effect •In summary the Hall effect gives a method for determining the mobility and the carrier concentration for both n-type and p-type semiconductors without the need of … WebApr 15, 2010 · The basic physical principle underlying the Hall effect is the Lorentz force, which is a combination of two separate forces: the electric force and the magnetic force. When an electron moves along the electric field direction perpendicular to an applied magnetic field, it experiences a magnetic force - qv X B acting normal to both directions.
