ElectroMagnetic InductionHard
Question
A conducting rod PQ of length 5 m oriented as shown in figure is moving with velocity (2m /s) î without any rotation in a uniform magnetic field (3ĵ + 4
) Tesla. Emf induced in the rod is
) Tesla. Emf induced in the rod isOptions
A.32 volt
B.40 volt
C.50 volt
D.None
Solution
e = Blv
where all the three should be perpendicular to each other
e =
⇒ e = (3ĵ + 4
) [(3î + 4ĵ) × 2î]
= (3ĵ + 4
)(8
) ⇒ e = 32 volt
where all the three should be perpendicular to each other
e =
⇒ e = (3ĵ + 4) [(3î + 4ĵ) × 2î]= (3ĵ + 4
)(8) ⇒ e = 32 voltCreate a free account to view solution
