Vedclass · Answer

(B) The net magnetic force on a current-carrying loop placed in a uniform magnetic field is zero. Therefore,the loop cannot undergo translational motion. This eliminates options $(C)$ and $(D)$.Using Fleming's left-hand rule,we can determine the direction of the magnetic force $\vec{F}_m$ on each small element of the loop. Given that the magnetic field is directed perpendicularly into the plane of the paper and the current flows in a clockwise direction,the magnetic force on every element of the loop acts radially outwards. Consequently,the loop will have a tendency to expand.

$A$ conducting loop carrying a current $I$ is placed in a uniform magnetic field pointing into the plane of the paper as shown. The loop will have a tendency to
