A vertical rod of length l is moved with constant velocity v towards east. The vertical component of earth magnetic field is B and angle of dip is theta. What is the induced emf in the rod?

Question

Ritik · Answer

Induced EMF is given by E= Blv ......1 Vertical component of B is B sin theta From 1 ,we getE= (B sin theta)× L× v cos theta E= B/v cot theta

A vertical conducting rod of length l is moved at a constant velocity v eastward. The vertical component of the Earth's magnetic field is B and the angle of dip is theta . ... The rod is vertical and moves east ward, therefore it 'cuts' horizontal component Bh of the magnetic field .

Naman Agrawal · Answer

From the above figure, are conclude that magnetic force which is responsible for induction of emf is horizontal component of magnetic field only. Formula Δ e = ( V ˉ × B ˉ ) l = V B l sin 9 0 ∘ = V B l Now tan θ = B B H ​ ​ ⇒ B H ​ = B cot θ Now, emf induced = e = V ( B H ​ l ) e = V B l cot θ ⇒ e = B l v cot θ
