What do you understand by electric flux?
electric flux, property of an electric field that may be thought of as the number of electric lines of force (or electric field lines) that intersect a given area. The negative flux just equals in magnitude the positive flux, so that the net, or total, electric flux is zero.
How do I know my electric flux?
Know the formula for electric flux.
- The Electric Flux through a surface A is equal to the dot product of the electric field and area vectors E and A.
- The dot product of two vectors is equal to the product of their respective magnitudes multiplied by the cosine of the angle between them.
How is magnetic flux used in everyday life?
Computer hard drives use magnetism to store the data on a rotating disk. More complex applications include: televisions, radios, microwave ovens, telephone systems, and computers. An industrial application of magnetic force is an electromagnetic crane that is used for lifting metal objects.
What is electric flux in class 12th?
Electric flux – Electric flux is the measure of number of electric field lines passing through any surface . It is a scalar quantity. It’s S.I unit is volt meters. Gauss Law- It is defined as the total flux linked within a closed surface is equal to the 1ε0 times the total charge enclosed by that surface.
What is flux in physics class 11?
Flux Definition Physics We define the Electric Flux as the rate of flow of the electric field through a given area and it varies directly with the number of electric field lines going via a virtual surface.
How do you know if electric flux is positive or negative?
Where by net number we mean the number leaving the surface minus the number entering the surface. If more lines are leaving than entering the flux is positive and if more lines are entering than leaving the flux is negative.
Why do we calculate flux?
It is a useful tool for helping describe the effects of the magnetic force on something occupying a given area. The measurement of magnetic flux is tied to the particular area chosen. We can choose to make the area any size we want and orient it in any way relative to the magnetic field.
What is the example of electric flux?
The total number of electric field lines passing through a given area in a unit time is the electric flux….\phi = E A \;cos\theta.
| \phi | Electric flux |
|---|---|
| E | The magnitude of the electric field |
| A | Area of the surface |
| \theta | The angle between the plane and the axis parallel to the direction of flow of the electric field. |
