Question

The current carrying wire and the rod $AB$ are in the same plane. The rod moves parallel to the wire with a velocity $v$. Which one of the following statement is true about induced e.m.f. in the rod?

• A. End $A$ will be at lower potential with respect to $B$
• B. $A$ and $B$ will be at the same potential
• C. There will be no induced e.m.f. in the rod
• D. Potential at $A$ will be higher than that at $B$

Answer 1

The correct option is D Potential at $A$ will be higher than that at $B$

According to fleming's right hanf rule,Potential at A will be higher than that at B.

so that the correct option is D.
