Consider a small vector area element Δ S of a closed surface S as shown in figure. The magnetic flux through Δ S is defined as Δ φB= B ⋅ Δ S where, B is the field at Δ S.

Q. Consider a small vector area element $Δ S$ of a closed surface $S$ as shown in figure. The magnetic flux through $Δ S$ defined as $Δ ϕ_{B}$ is

$B \cdot Δ S$

$2 B \cdot Δ S$

$B \cdot 2Δ S$

$B \times Δ S$
