Vedclass · Answer

(B) When a metal rod of length $l$ moves with velocity $v$ in a uniform magnetic field $B$ such that $v$,$B$,and $l$ are mutually perpendicular,the Lorentz force $F = q(v 	imes B)$ acts on the free electrons in the rod.This force causes electrons to accumulate at one end of the rod,leaving the other end positively charged.This separation of charges creates an internal electric field $E$ within the rod,which opposes further movement of charges.Thus,there is an electric field present in the rod,and a potential difference is developed across its ends.

$A$ metal rod moves at a constant velocity in a direction perpendicular to its length. $A$ constant uniform magnetic field exists in space in a direction perpendicular to the rod as well as its velocity. Select the correct statement from the following:
