alleryStart learning →A rod moves along the field lines of a uniform field. What is its motional emf?
AZero, no lines are cut
BMaximum, equal to Blv
CHalf of the maximum
DInfinitely large value
Answer & Solution
Correct answer: A. Zero, no lines are cut
Motional emf is Blv sin(theta) and theta is zero here, so no emf appears.
