ElectroMagnetic InductionHard
Question
A conducting rod of length l rotates with a uniform angular velocity w about its perpendicular bisector. A uniform magnetic field B exists parallel to the axis of rotation. The potential difference between the two ends of the rod is
Options
A.2Bωl2
B.1/2Bωl2
C.Bωl2
D.zero
Solution
Since magnetic field lines around the wire AB are circular, therefore magnetic flux through the circular loop will be zero, hence induced emf in the loop will be zero.
