Luminous flux is measured in lumens (symbol: lm).
Tesla.
Flux is the number of lines or particle passing per unit area. The unit of area is meter square.
"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.
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
Luminous flux is measured in lumens (symbol: lm).
Luxmeter measures luminous intensity. The SI unit of luminous intensity is candela (cd).
Candela (cd).
Lux is used in measuring luminous flux per unit area.
Lumen is a unit of luminous flux, while candlepower (or candelas) is a unit of luminous intensity. The conversion between lumen and candlepower depends on the directionality of the light source. For the radiant intensity of a uniform point source of light, 1 candela is equivalent to 1 lumen per steradian (lm/sr).
The formula for working out luminous intensity is luminous flux divided by solid angle. Mathematically, luminous intensity (I) = luminous flux (Φ) / solid angle (Ω). Luminous intensity is measured in candelas (cd), luminous flux in lumens (lm), and solid angle in steradians (sr).
Lumens measure the total quantity of visible light emitted by a source per unit of time. It is a unit used to quantify the overall brightness of a light source visible to the human eye, irrespective of the direction in which the light is emitted.
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'.
A unit of magnetic flux is called a Weber.
In the SI the unit of luminous intensity is candela(cd).
The SI unit of attractive flux is the weber (Wb). The CGS unit is the maxwell.
The unit of flux per pole is Weber (Wb).
