Noun
Hall effect (plural Hall effects)
(physics) the effect in which a conductor that carries an electric current perpendicular to an applied magnetic field develops a voltage gradient transverse to both current and field
Advantages over other methods Hall effect devices (when appropriately packaged) are immune to dust, dirt, mud, and water. Source: Internet
For sufficiently strong B-fields, each Landau level may have so many states that all of the free electrons in the system sit in only a few Landau levels; it is in this regime where one observes the quantum Hall effect. Source: Internet
Hall effect main The charge carriers of a current carrying conductor placed in a transverse magnetic field experience a sideways Lorentz force; this results in a charge separation in a direction perpendicular to the current and to the magnetic field. Source: Internet
For example, positive Hall effect was observed in evidently n-type semiconductors. Source: Internet
Electric motor control Some types of brushless DC electric motors use Hall effect sensors to detect the position of the rotor and feed that information to the motor controller. Source: Internet
