When magnetic flux through surface is maximum?
Magnetic flux through a surface is maximum when the direction of the magnetic field is in the same direction as the normal vector of the surface. In other words, the magnetic flux is maximum when the magnetic field is perpendicular to the surface area. That's why φ=BAcosθ, where θ is the angle between the direction of the magnetic field and the normal vector of the surface area. When the magnetic field is exactly the same direction as the normal vector (aka the magnetic field is perpendicular to the surface), θ=0 and cosθ = 1, its maximum value. The closer θ is to 90 degrees (ie. the more parallel the direction of the magnetic field is to the surface area, or the less parallel the magnetic field is to the surfaces normal vector), the smaller cosθ is, and thus flux will decrease accordingly.
What do you mean by electric flux in electrostatics?
Under an electric field, magnitude and direction of electric intensity is different in every point.If the electric intensity can be defined through a closed line (direction of electric intensity will be along the tangent of any point of that line)this is called electric lines of force. Electric lines of forces passing through an closed electric surface perpendicularly, is called electric flux.
What makes a material diamagnetic?
All materials naturally repel magnetic lines of flux but some materials, like iron, are attracted to magnetic flux because they have unpaired electrons that are attracted to the lines of flux.
How do you calculate magnetic flux density?
'Magnetic field strength' (symbol: H) is defined as 'the magnetomotive force, per unit length, of a magnetic circuit'. In SI, it is expressed in amperes per metre (A/m), which is often spoken as "'ampere turns' per metre".It's equation is: H = (IN) / lwhere:H = magnetic field strength (ampere per metre)I = current flowing through coil (amperes)N = number of turns in coill = length of magnetic circuit
What does the Earths magnetic field resemble?
The Earth's magnetic field resembles that of a bar magnet, with lines of flux that radiate from the poles and loop back into the planet near the equator. This field is created by movements in the Earth's outer core, primarily composed of molten iron and nickel.
What is flux density related to?
In case of electrostatics, flux density = electric field intensity and in case of magnetism, flux density = magnetic field induction
What is the direction of flux in a magnetic field?
The direction of flux in a magnetic field is perpendicular to both the magnetic field lines and the surface it passes through.
Relationship between flux density and field strength?
In simple terms, if flux density increases, then field strength increases and vice versa. The flux density is equivalent to field strength times with a variable.
What is the direction of magnetic flux in a magnetic field?
The direction of magnetic flux in a magnetic field is from the north pole to the south pole.
What is Magnetic flux density unit?
"Magnetic flux density" is also known as the magnetic field,The SI unit for this is the Tesla, written as T.CommentMagnetic flux density is not "also known as the magnetic field". It describes the intensity of a magnetic field.
How do you calculate total flux when flux density and magnetic field strength has been?
once flux density is known multiply to it the area perpendicular to the flux lines . the product is the total flux passing through the area. If field strength is known , get the flux density by pultiplying to it the permeability of the medium. then flux can be obtained as above. from : govind Kunkolienker kunkolienker@yahoo.com
What are the factors upon electric flux depends on?
Electric flux depends on the strength of the electric field, the angle between the electric field and the surface, and the area of the surface the electric field passes through. Additionally, the distribution of charges within the field also affects the electric flux.
What is the formula for magnetic flux and how is it calculated?
The formula for magnetic flux is B A cos(), where is the magnetic flux, B is the magnetic field strength, A is the area of the surface, and is the angle between the magnetic field and the surface normal. Magnetic flux is calculated by multiplying the magnetic field strength, the area of the surface, and the cosine of the angle between the magnetic field and the surface normal.
What is maximum and minimum electric flux?
As we know that electric flux is the total number of electric lines of forces passing through a surface. Maximum Flux: Electric flux through a surface will be maximum when electric lines of forces are perpendicular to the surface. Minimum flux: Electric flux through a surface will be minimum or zero when electric lines of forces are parallel to the surface.
How Flux linkage increase or decrease in coil?
Flux linkage in a coil increases when the magnetic field strength or the number of turns in the coil increases, resulting in more magnetic field lines passing through the coil. Conversely, flux linkage decreases if the magnetic field strength weakens or if the coil is moved away from the magnetic field source. Additionally, changes in the orientation of the coil relative to the magnetic field can also affect flux linkage. In summary, the factors that influence flux linkage include magnetic field strength, coil turns, and coil positioning.
Is magnetic flux the same as the magnetic feld?
magnetic field is a imaginary area around a manetic material where other magnetic subestences experience some force but flux is the imaginary lines of force that arise from magnet which indicate direction of force around it.
How is the magnetic field related to the Poynting flux in a charging capacitor?
The magnetic field is related to the Poynting flux in a charging capacitor through electromagnetic induction. As the capacitor charges, the changing electric field produces a magnetic field, which in turn affects the flow of energy in the form of electromagnetic waves known as the Poynting flux.
