Question

What is flux?

Answer 1

Flux:

1. Flux is defined as any effect that appears to pass or travel through a surface or substance.
2. Flux is an imaginary line through which a physical quantity can travel.
3. It can be thought of as imaginary lines through which a physical quantity can travel.
4. There are two types of flux that are used generally. They are magnetic flux and electric flux.
5. There are other types of fluxes present too.
6. In fluid dynamics, the volumetric flux is the rate of volume flow across a unit area.
7. Radiant flux refers to the line of transmitted radiated energy per second from any energy source.

Electric flux:

1. It can be defined as the measure of the total electric field that can pass through an area.
2. It is the dot product of electric field $\left(\overrightarrow{E}\right)$ and surface area $\left(\overrightarrow{S}\right)$.
3. The mathematical expression for electric flux is ${\varphi }_E=\overrightarrow{E}·\overrightarrow{S}=ES\cos \theta$, where $\theta$ is the angle between electric field lines and the area vector.

Magnetic flux:

1. It can be defined as the measure of the total magnetic field that can pass through an area.
2. Flux is a vector quantity that can be defined as the rate that relies on the direction of the magnetic field.
3. It is the dot product of the magnetic field $\left(\overrightarrow{B}\right)$ and area of cross section $\left(\overrightarrow{A}\right)$.
4. The mathematical expression for magnetic flux is ${\varphi }_M=\overrightarrow{B}·\overrightarrow{A}=BA\cos \theta$, where $\theta$ is the angle between magnetic field lines and the area vector
