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 statements is true about induced emf in the rod 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 statements is true about induced emf in the rod
A
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 emf in the rod
D
Potential at A will be higher than that at B
Answer
Potential at A will be higher than that at B
Explanation
Solution
According to Fleming's right hands rule direction of induced current in rod is from B to A i.e. end A is at higher potential.
