Question

A loop of area $4m^2$ is placed flat in the x-y plane.There is a constant magnetic field $4T\hat{j}$ in the region. Find the flux through the loop

• A. $2units$
• B. $4units$
• C. $6units$
• D. $0units$

Answer 1

The correct option is D $0units$

The loop is kept in the x-y plane and the magnetic field is in the direction of y axis . Thus the flux through the loop is given by $\varphi =B.A=4T\hat{j}.4\hat{k}$

$=0$units.
