Why is flux a scalar quantity and the dot product of magnetic field and area?

As we are using dot products, the magnetic flux is a scalar quantity. When the magnetic field is along the area of the closed surface, the magnetic flux is 0. It happens because the angle between the area vector and the magnetic field vector is 90°.

How flux is a scalar quantity?

In other words, electric flux is the measure of how many electric field lines are passing through the surface. Electric flux is a scalar quantity because it is the dot product of two vector quantities, the electric field, and the perpendicular differential area.

Why is the electric field a vector quantity while the electric potential is a scalar?

Because it’s derived from a force, it’s a vector field. The electric potential is the electric potential energy of a test charge divided by its charge for every location in space. Because it’s derived from an energy, it’s a scalar field.

Is electric flux scalar quantity or vector quantity?

It is a dot product of electric field vector (vector E) and area vector (vector ds). As it is a dot product. So, electric flux is a scalar quantity.

Is flux scalar or vector quantity?

For transport phenomena, flux is a vector quantity, describing the magnitude and direction of the flow of a substance or property. In vector calculus flux is a scalar quantity, defined as the surface integral of the perpendicular component of a vector field over a surface.

Why magnetic flux is a dot product?

Flux is the amount of magnetic field that is “flowing” through a given surface. So you only want to calculate with the component of B that is perpendicular to the surface. Hence the dot product.

Is magnetic flux a vector quantity?

Magnetic flux is a scalar quantity. The other related quantity, magnetic flux density, denoted by B, is a vector quantity. Magnetic flux is the surface integral of the normal component of B across the surface.

Is electric flux a scalar or vector quantity give reason?

Is electric field a scalar quantity?

No, electric field is not a scalar. The electric is a vector quantity. We know that electric field is the ratio of force per unit test charge. Since, force is a vector quantity, electric field is also a vector quantity.

Is electric potential A vector quantity or a scalar quantity?

Electric force and electric field are vector quantities (they have magnitude and direction). Electric potential turns out to be a scalar quantity (magnitude only), a nice simplification.
