When magnetic flux is maximum?
The magnetic flux through the plane of the coil has its maximum value when this plane is perpendicular to the magnetic field lines between the poles.
As the coil turns and the plane of the coil becomes parallel to the field lines, the flux becomes zero..
Does flux have direction?
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.
How do you find magnetic flux?
ΦB=B⋅A=BAcosθ Φ B = B ⋅ A = BA cos , where B is the magnitude of the magnetic field (having the unit of Tesla, T), A is the area of the surface, and θ is the angle between the magnetic field lines and the normal (perpendicular) to A.
Does flux depend on area?
The flux of a vector field through a surface area is the amount of whatever the field represents passing through the area. The total flux depends on strength of the field, the size of the surface area it passes through, and on how the area is oriented with respect to the field.
What is flux with example?
Flux is the presence of a force field in a specified physical medium, or the flow of energy through a surface. In electronics, the term applies to any electrostatic field and any magnetic field . Flux is depicted as “lines” in a plane that contains or intersects electric charge poles or magnetic poles.
What is the difference between flux and flow?
As nouns the difference between flow and flux is that flow is the movement of a fluid while flux is the act of flowing; a continuous moving on or passing by, as of a flowing stream.
What is the electric flux through a cube of side 1 cm?
Answer Expert Verified the net electric charge inside the closed cubic surface = 0, as the dipole consists of equal and opposite charges. The net electric flux through a closed 3-d surface = charge enclosed/epsilon. So net electric flux = 0.
What is flux formula?
Electric Flux Formula. The electric flux through a planar area is defined as the electric field times the component of the area perpendicular to the field. Electric flux = Electric field * Area * (angle between the planar area and the electric flux) The equation is: Φ = E A cos(θ)
Can you have negative flux?
The negative flux just equals in magnitude the positive flux, so that the net, or total, electric flux is zero. … If a net charge is contained inside a closed surface, the total flux through the surface is proportional to the enclosed charge, positive if it is positive, negative if it is negative.
Is electric flux a vector quantity?
Electric flux is a scalar quantity. It is a scalar because it is the dot product of two vector quantities, electric field and the perpendicular differential area.
What does flux mean?
The noun flux describes something that constantly changes. If your likes, dislikes, attitudes, dreams, and even friends are changing all the time, you may be in flux. Flux can also mean being unsure about a decision.
What is electric flux and its unit?
Electric Flux: Electric flux is a number of electric lines of forces which posses through any cross sectional area when the cross sectional area in kept perpendicular to the direction of electric field. Electric flux is scalar quantity which is denoted by ΦE. S.I. Unit is Neutron(metre2/ coulomb) NM˙2/C.
Is flux positive or negative?
Remember our convention for flux orientation: positive means flux is leaving, negative means flux is entering. In this example, water is falling downward, or entering the tube. This means the top surface has negative flux (it appears to be siphoning up water).
What is flux density formula?
Flux density is simply the total flux divided by the cross sectional area of the part through which it flows – B = Φ / Ae teslas. Thus 1 weber per square metre = 1 tesla. Flux density is related to field strength via the permeability. B = μ × H.
Does electric flux depend on medium?
Yes, the medium affect the electric flux. Vacuum permitivity relates the relative effect against that of an ideal vacuum.
Does flux depend on volume?
Gauss’s law of electricity, which is included within the fundamental laws of electromagnetism, states that the electric flux through a closed surface with electric charge inside, just depends on the net charge enclosed in the surface and does not depend the shape or size of the surface.
Can electric field be negative?
Electric field is not negative. It is a vector and thus has negative and positive directions. An electron being negatively charged experiences a force against the direction of the field. For a positive charge, the force is along the field.
How is flux measured?
The SI unit of magnetic flux is the weber (Wb; in derived units, volt–seconds), and the CGS unit is the maxwell. Magnetic flux is usually measured with a fluxmeter, which contains measuring coils and electronics, that evaluates the change of voltage in the measuring coils to calculate the measurement of magnetic flux.
