If i have a current of both negative and positive charges(i know that there is also current from only negative and only positive charges,i'm not confused) along an infinite wire of square cross-section,and the we put a homogeneous magnetic field normal to the current,then a Lorentz force acts on both the positive and negative charges and it is in the same direction for both of them(negative charges move in the opposite direction of the positive charges so from the equation of the Lorentz force,the negative sign from the negative charge and the negative sign from the velocity vector cancel each other out-considering positive velocity vector in the direction that the positive charges are moving).But because the forces act in the same direction AND because negative and positive charges attract each other,then we will have accumulation of both negative AND positive charges on near the one end of the wire.So,the question is,will there be a potential difference transverse of the wire like the normal classical Hall effect?(adsbygoogle = window.adsbygoogle || []).push({});
