Question

The amount of flux in a round magnetic rod measured at 0.013 weber.If the diameter of the material is 12 cm, calculate the flux density?

Answer 1

Solution

Given data

Flux $(\Phi) =0.013$ Webers

Diameter=12cm

Radius(r) =6cm=0.06m

Area(A) =$\pi r^2 =3.14\times0.06\times0.06$

=0.0113 $m^2$

Flux density can be expressed as

$B=\frac{\Phi}{A}=\frac{0.013}{0.0113}=1.15Tesla$

Therefore flux density is 1.15 T.
