When a current-carrying wire is placed in a transverse magnetic field, a macroscopic force and a transverse Hall electric field are generated. An experimental and theoretical study of the role of the Hall electric field on the generation of the force on the current-carrying wire was conducted employing single-carrier, conventional bipolar type conductors, and unusual bipolar type conductors, in which an approximately zero Hall electric field is expected. It is shown theoretically and experimentally that the collisions of the carrier with the ions solely contribute to the Lorentz force transmission mechanism in the unusual bipolar type conductors, whereas the action of collisions of the carrier with ions as well as the action of the Hall electric field on the lattice ions is responsible for transmission of the Lorentz force in the usual bipolar conductors. A self-consistent treatment of the generation of the Hall electric field is given.
