Question

A metallic block carrying current i is subjected to a uniform magnetic induction   as shown in the figure. The moving charges experience a force   given by ........... which results in the lowering of the potential of the face ........ Assume the speed of the carriers to be v

Infinity Learn · Accepted Answer

As the block is of metal, the charge carriers are electrons, so for current along positive $$x-axis$$, the electrons are moving along negative $$x-axis$$, i.e. and as the magnetic field is along the $$y-axis$$, i.e.  so   for this case yield  i.e.,    [As   As force on electrons is towards the face ABCD, the electrons will accumulate on it and hence it will acquire lower potential
