A square of side L m lies in XY plane in a region, where the magnetic field is given by $B = B_0(2\hat i+3\hat j+4\hat k)T$ and $B_0$ a constant. The magnitude of the flux passing through the square is: |
$2 B_0 L^2 Wb$ $3 B_0 L^2 Wb$ $4 B_0 L^2 Wb$ $\sqrt{29} B_0 L^2 Wb$ |
$4 B_0 L^2 Wb$ |
The correct answer is Option (3) → $4 B_0 L^2 Wb$ The magnetic flux $(\phi)$ through a surface is - $\phi=\vec B.\vec A$ $=B_0(2\hat i+3\hat j+4\hat k).(L^2\hat k)$ $=4 B_0 L^2 Wb$ |
