What is 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. Electric field lines are considered to originate on positive electric charges and to terminate on negative charges.

What is electric flux class 12th?

The total number of electric field lines passing a given area in a unit of time is defined as the electric flux.

What is electric flux and its unit?

Electric flux can be defined as the measure of the distribution of the electric field or the rate of flow of the electric field through a given area. Electric flux is denoted by the greek symbol . The SI unit of electric flux is or Nm 2 C - 1 .

What is electric flux example?

Solved Examples 1: A planar surface has an area of 1 square meter. If an electric field crosses with an angle of 60^{\circ} to it and has E= 2 Volte per meter.

What is the SI unit of flux?

The SI unit of magnetic flux is the Weber (Wb). A flux density of one Wb/m2 (one Weber per square metre) is one Tesla (T).

What is a flux easy definition?

Definition of flux noun. a flowing or flow. the flowing in of the tide. continuous change, passage, or movement: His political views are in a state of flux.

What is electric flux BYJU's?

Electric flux is a property of an electric field defined as the number of electric lines of force (or electric field lines) that intersect a given area. Electric field lines are thought to start with positive charges and end with negative charges.

Is weber SI unit of electric flux?

weber, unit of magnetic flux in the International System of Units (SI), defined as the amount of flux that, linking an electrical circuit of one turn (one loop of wire), produces in it an electromotive force of one volt as the flux is reduced to zero at a uniform rate in one second.

What is electric flux write its formula?

Solution. Electric flux through a surface in an electric field is defined as the total number of electric lines of force crossing the surface in a direction normal to the surface. Its SI unit is N m2 C−1. Report Error Is there an error in this question or solution?

What is Gauss's law class 12?

Gauss Law states that the total electric flux out of a closed surface is equal to the charge enclosed divided by the permittivity. The electric flux in an area is defined as the electric field multiplied by the area of the surface projected in a plane and perpendicular to the field.

What is current flux?

In Electromagnetism, the electric field is defined as the measure of the flow of electric current through a given area. It is a property of an electric field that may be thought as electric field lines that intersect at a particular area.

What is the SI unit of electric flux 12?

SI Unit of Electric Flux Talking about the unit, the SI base unit of electric flux is volt-metres (V m) which is also equal to newton-metres squared per coulomb (N m2 C-1).

What is the symbol for flux?

The Greek letter Phi suffix B or Phi is generally used to denote the magnetic flux. The symbol of magnetic flux is ΦB or Φ.

Is electric flux a vector?

since, electric field is a vector quantity and the area is also a vector quantity, the dot product of two vectors is always a scalar quantity. Hence, Electric flux is a scalar quantity not a vector quantity.

Why electric 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.

What is meant by Lenz law?

Lenz's law states that. The induced electromotive force with different polarities induces a current whose magnetic field opposes the change in magnetic flux through the loop in order to ensure that the original flux is maintained through the loop when current flows in it.

Can flux be negative?

Recall that electric flux is proportional to the number of electric field lines crossing a surface. For a closed surface, electric field lines will be either entering or leaving the surface and thus the corresponding flux may be positive or negative.

How is flux produced?

When a coil of wire is moved through a magnetic field a voltage is generated which depends on the magnetic flux through the area of the coil. This is described by Faraday's law and is explored in our article on Faraday's law.

What is flux made of?

flux, in metallurgy, any substance introduced in the smelting of ores to promote fluidity and to remove objectionable impurities in the form of slag. Limestone is commonly used for this purpose in smelting iron ores. Other materials used as fluxes are silica, dolomite, lime, borax, and fluorite.

What is flux used for?

What is Flux? Flux aids in soldering and desoldering processes by removing oxide films which form on the surface of metals being soldered. It increases the wetting ability of the solder, causing it to flow more uniformly over surfaces without balling-up (dewetting).
