A square frame ABCD, made of copper wire is made to move with a velocity V parallel to the diagonal DB in a uniform magnetic field of induction ‘B’ as shown in figure. Induced potential difference between points A and D is $$2$$ volt. Then select the correct option.

Question

Infinity Learn · Accepted Answer

Component  of V→ perpendicular to AD is V $$sin$$ $$45o$$. If l be the length of side of the square, then $$VA-VD=BlV$$ $$sin45o$$.∴ BlV.$$sin45o=2$$⇒$$BlV=22$$ voltVelocity V→ is perpendicular to the diagonal AC.∴ VA−$$VC=BACV=B2lV=2BlV=2$$×$$22$$ volt⇒VA−$$VC=4$$ voltSince velocity V→ is parallel to the diagonal BD, $$VB-VD=0$$.
