    Figure represents an area \[A=0.5\,\,{{m}^{2}}\] situated in a uniform magnetic field \[B=2.0\,\,Wb/{{m}^{2}}\] and making an angle of \[{{60}^{o}}\] with respect to magnetic field. The value of magnetic flux through the area will be

    A)  0.5 Wb

    B)  \[\sqrt{3}\] Wb

    C)  \[\frac{3}{2}\] Wb             

    D)  2.0 Wb

    Correct Answer: A

    Solution :

    \[As\,\phi =B\,.\,A\] \[\Rightarrow \] \[\phi =2\times 0.5\times \cos {{60}^{o}}\] \[=2\times 0.5\times \frac{1}{2}=0.5\,Wb\]
