The infinitely long straight current carrying wire and the 
are in the same plane. According to diagram, the rod moves parallel to the wire with a velocity 
. Which one of the following statements is true about induced emf in the rod?
will be at lower potential with respect to end 
. 
and 
will be at the same potential. 
will be at higher potential with respect to end 
.

Using the Right-Hand Thumb Rule, the magnetic field ( 
) experienced by the rod is directed into the page.
Since, electrons are negatively charged, meaning the force on the electrons is directed downwards, towards end B.
Due to the downward force on the electrons, electrons will accumulate at end B , making end B negatively charged. Consequently, A is positively charged and end B is negatively charged, end A will be at a higher potential with respect to end 
.
