Qstn# 7-a Prvs-QstnNext-Qstn
  • #7-a
    What is the instantaneous value of the emf induced in the wire?
    (b) What is the direction of the emf?
    (c) Which end of the wire is at the higher electrical potential?
    Ans : Emf induced in the wire,

    e = Blv


    (b) Using Fleming’s right hand rule, it can be inferred that the direction of the induced emf is from West to East.
    (c) The eastern end of the wire is at a higher potential.
