 # Unit of Magnetic Flux

Magnetism is indeed a vast chapter for students with a lot of topics and concepts to cover. However, on this page, we will discuss the unit of magnetic flux.

Well, in simple terms magnetic flux is defined as a measure of the strength of a magnetic field over a given area. It has the dimension mass length squared per time squared electric current. It is denoted by Greek letters Phi and has a symbol φ. Further, magnetic flux is basically used to describe the effects of the magnetic force on something occupying a given area. Now let’s look at the magnetic flux units.

## SI Unit of Magnetic Flux

The SI unit of magnetic flux is the weber (Wb). A flux density of one Wb/m2 (one weber per square metre) is one tesla (T). Weber is commonly expressed in a multitude of other units.

$Wb = \frac{kg.m^{2}}{s^{2}.A} = V.s = H.A = T.m^{2} = \frac{J}{A} = 10^{8}M.x$

where,

• Wb = Weber
• T = Tesla
• V = volt
• m = metre
• J = joule
• s = second
• H = Henry
• A = ampere
• Mx = Maxwell

The unit has also been named after German physicist, Wilhelm Eduard Weber.

#### Other Common Units

In the CGS unit of magnetic flux is measured in Abweber or Maxwell. Other units include statweber and unit_pole.
