The value of magnetic field induction which is uniform is 2T. What is the flux passing through a surface of area 1.5 ${{m}^{2}}$ perpendicular to the field ?


#2

Magnetic induction of uniform field B = 2T Surface area A = 1.5 ${{m}^{2}}$
Flux $\phi $ = ?

We know B = $\phi $/A => $\phi $ = BA cos $\theta $
$ \phi$ = BA
Where B is perpendicular to area Is.
$\triangle$$ \phi$ = 2 x 1.5 = 3 webers.
