The magnetic field in a region is given by $\overset{\to}{B} = {B}_{0}\left(\dfrac{x}{a}\right)\overset{^}{k}$ . A square loop of side d is placed with its edges along the $x$ and $y$ axes. The loop is moved with a constant velocity $\overset{\to}{v} = {v}_{0}\overset{^}{i}$ . The emf induced in the loop is :

Question

The magnetic field in a region is given by → B = B _ 0 ((x)/(a)) ^ k . A square loop of side d is placed with its edges

Quantrex Academy · Accepted Answer

Correct answer: C. B _ 0 v _ 0 d ^ 2 a

E _ 1 = B _ 0 (x + d) a v _ 0 d E _ 2 = B _ 0 (x) a v _ 0 d E _ net = E _ 1 - E _ 2 E _ net = B _ 0 v _ 0 d ^ 2 a

The magnetic field in a region is given by → B = B _ 0 ((x)/(a)) ^...
