What is flux density and how it is related to the number of lines of induction expressed in webers?
Flux density is the number of magnetic lines crossing per unit area in perpeendicular direction. It is named as manetic field induction, B. Unit is tesla or weber/m2 Unit for magnetic flux is weber in SI system. Fl
Why the flux density is in square meters not meter cube?
Flux is the number of lines or particle passing per unit area. The unit of area is meter square.
What is the Si Unit of luminous flux?
Luminous flux is measured in lumens (symbol: lm).
1 A Gaussian surface in the shape of a right circular cylinder with end caps has a radius of 12.0cm and a length of 80.0cm Through one end there is an inward magnetic flux of 25.0µWb At the other e?
Using the Gauss' Law of Magnetism We know total flux will be zero flux(top)+flux(bottom)+flux(curved side)=0 ------- (a) flux(bottom)= -25e-3 (GIVEN) (-ve shows inward direction) flux(top)=B*A=(1.6e-3)*[3.14*(0.12)^2]=2.304e-5 Put the values in eq (a) you'll get flux(curved side)= +24.97e-3 (+ve shows direction is outward)
What will happen if height to width ratio of the window of core-type transformer is increased?
Then the leakage flux will be reduced as leakage flux is iversely propertional to window factor i,e height to width ratio of the window. As height is more & width is less then the leakage flux ll travel through low reluctance path i,e core itself and it adds with the main flux or working flux.
Why flux is maximum when area is perpendicular to electric field?
When the area is perpendicular to the electric field, the maximum number of electric field lines pass through the area, resulting in the maximum flux. This occurs because the angle between the electric field lines and the normal to the area is at its smallest, maximizing the dot product that determines flux.
Who discovered magnetic lines of flux?
Faraday, proposed lines of flux and lines of force.
What direction do magnetic flux lines travel from?
Magnetic flux lines travel from the north pole of a magnet to the south pole.
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.
What is flux fringing and where does it occur?
The lines of flux are crowded at the ends of magnets, this phenomena is called fringing.
Can weld without flux is possible?
You can arc weld & then the flux will be in the rod.
What are lines of flux?
Flux is the presence of a force field in a specified physical medium, or the flow of energy through a surface.
Why is a magnet strongest at poles?
That is where the imaginary "flux lines" are concentrated.
What do Flux lines do?
There is more magnetic force in that region on a particle.
How the electricity is obtained?
By cutting lines of magnetic flux through an electromagnet
The unseen lines of force round a magnet are called?
Magnetic flux
What are magnetic lines of forces?
Electro magnetic flux which is in maxwells and gauss.
