## How do you find area vector?

Hence, for a simple rectangular plate defined by two vectors →a and →b the vector area is described as:

1. →A=→a×→b.
2. →A=∫Sd→S.
3. ∮Sd→S=→0.

## How do you find the area of a vector in a magnetic field?

The orientation of the area vector can be found by applying a right-hand rule. Curl the fingers on your right hand in the direction of the current flow. Your thumb, when you stick it out, gives the direction of the area vector.

## How do you solve electric flux?

Solution: electric flux is defined as the amount of electric field passing through a surface of area A with formula Φ e = E ⃗ ⋅ A ⃗ = E A cos ⁡ θ Phi_e=vec{E} cdot vec{A}=E,A,costheta Φe=E ⋅A =EAcosθ where dot ( ⋅) is the dot product between electric field and area vector and θ is the angle between E and the …

## What do you mean by area vector?

: the vector of a plane surface whose magnitude is the area of the figure and whose direction is that of a perpendicular to the plane of the figure.

## What is the unit of area vector?

Consider the surface S defined by the Ampèrian loop ∂S. Then, a vector normal to this surface and with magnitude equal to the area of the surface is →a. This is commonly referred to as the vector area of S. Then, the unit vector ˆa is a vector parallel to →a, but with unit length.
