ElectroMagnetic InductionHard
Question
A vertical rod of length l is moved with constant velocity v towards East. The vertical component of the earth′s magnetic field is B and the angle of dip is θ. The induced e.m.f. in the rod is :
Options
A.B l v cot θ
B.B l v sin θ
C.B l v tan θ
D.B l v cos θ
Solution
BH = B cos θ
BV = B sin θ
BH = BV cot θ.
BV = B sin θ
BH = BV cot θ.
