Question

An electric potential difference will be induced between the ends of the conductor shown in the figure, if the conductor moves in the direction shown by :

• A. P
• B. R
• C. L
• D. M

Answer 1

The correct option is D M

Electric potential difference will be induced when there is charge separation in the conductor due to force by magnetic field, which is given by $F=q(V\times B)$
So, to have $F$ equal to non-zero, conductor should move perpendicular to the direction of B. Now, since B's direction is along L to R. So, v should be in direction of M, so we have to move conductor in
direction M.
