    A current carrying conductor is looped into a circle of radius 10cm. The magnetic moment of the current loop becomes\[0.314\text{ }{{m}^{2}}\]. What is the current in the loop:

    A)  \[5\,A\]                       

    B)  \[8\,A\]

    C)  \[10\,A\]                     

    D)  \[12\,A\]

    Correct Answer: C

    Solution :

    As the magnetic moment \[M=iA\] So from the question             \[3.14\times {{10}^{-1}}=i\times 3.14\times 0.01\]             \[i=10A\]
