    If a change in current of 0.01 A in one coil produces a change in magnetic flux of \[1.2\times {{10}^{-2}}Wb\] in the other coil, then the mutual inductance of the two coils in henries is [EAMCET 2001]

    A)            0    

    B)            0.5

    C)            1.2 

    D)            3

    Correct Answer: C

    Solution :

               \[\varphi =Mi\Rightarrow M=\frac{1.2\times {{10}^{-2}}}{0.01}=1.2H\]
