Which of the following do not exist?

$A$ square of side $L$ meter lies in the $x-y$ plane in a region where the magnetic field is given by $\overrightarrow{B} = B_0(2 \hat{i} + 4 \hat{j} + 3 \hat{k}) \text{ T}$,where $B_0$ is a constant. The magnitude of the magnetic flux passing through the square is . . . . . . .

$A$ loop,made of straight edges,has four corners at $A(L, L, 0)$,$B(-L, L, 0)$,$C(-L, -L, 0)$,and $D(L, -L, 0)$. $A$ magnetic field $\vec B = B_0(\hat i + \hat k) \text{ T}$ is present in the region. The magnetic flux passing through the loop $ABCD$ is:

The radius of a coil of $N$ turns is $R$. If the plane of the coil is placed parallel to a uniform magnetic field $B$,then the flux linked with the coil is:

When does the magnetic flux become zero?

Consider a circular coil of wire carrying constant current $I$,forming a magnetic dipole. The magnetic flux through an infinite plane that contains the circular coil and excluding the circular coil area is given by $\phi_{i}$. The magnetic flux through the area of the circular coil area is given by $\phi_{0}$. Which of the following options is correct?
