φ= overset arrow B. overset arrow A The area vector overset arrow A is perpendicular to the surface. So, when the surface is parallel to the magnetic field, the angle between overset arrow B and overset arrow A is 90° . Hence φ=0 .

zero

small but not zero

infinite

large but not infinite

$ϕ = B \to . A \to$
The area vector $A \to$ is perpendicular to the surface. So, when the surface is parallel to the magnetic field, the angle between $B \to$ and $A \to$ is $9 0^{\circ}$ .
Hence $ϕ = 0$ .

ϕ=B→.A→ The area vector A→ is perpendicular to the surface. So, when the surface is parallel to the magnetic field, the angle between B→ and A→ is 90∘ . Hence ϕ=0 .

$ϕ = B \to . A \to$
The area vector $A \to$ is perpendicular to the surface. So, when the surface is parallel to the magnetic field, the angle between $B \to$ and $A \to$ is $9 0^{\circ}$ .
Hence $ϕ = 0$ .
