What is the Si Unit of luminous flux?
Luminous flux is measured in lumens (symbol: lm).
What is the unit of flux density?
Tesla.
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 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.
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
What is the Si Unit of luminous flux?
Luminous flux is measured in lumens (symbol: lm).
The si unit of luminous flux?
Candela (cd).
What instrument measures luminous intensity or flux?
Luxmeter measures luminous intensity. The SI unit of luminous intensity is candela (cd).
What is measured using lux?
Lux is used in measuring luminous flux per unit area.
Can you convert lumen to candle power?
Not directly, as you are comparing apples with oranges in two senses: (a) a lumen is an SI unit, whereas a candlepower is an Imperial unit, and (b) lumens are used to measure luminous flux, whereas candlepower is used to measure luminous intensity.

What is lumens value?
A lumen is a unit of luminous flux. It is represented by the abbreviation 'lm'.One lumen equals the amount of light emitted in a solid angle from a source that radiates to an equal extent in all directions.
What is illuminations?
Illuminance is another term for luminous-flux density which defines the intensity of the luminous flux arriving at a surface, measured in lumens per square metre, which is given the special name 'lux'.
Unit of Magnetic flux?
A unit of magnetic flux is called a Weber.
What is Si unit of luminous intensity?
In the SI the unit of luminous intensity is candela(cd).
What is the unit of the magnetic flux?
The SI unit of attractive flux is the weber (Wb). The CGS unit is the maxwell.
What is the unit of flux per pole?
The unit of flux per pole is Weber (Wb).
