    A co-axial cable which carrying equal current in opposite direction have cross section as shown in diagram. If \[{{B}_{1}}\] and \[{{B}_{2}}\] are the magnetic field at inner and outer point of cable then which relation is correct:-

    A)  \[{{B}_{1}}=0,\,{{B}_{2}}=0\]

    B)  \[{{B}_{1}}\ne 0,\,{{B}_{2}}\ne 0\]

    C)   \[{{B}_{1}}=0,\,{{B}_{2}}\ne 0\]

    D)  \[{{B}_{1}}\ne 0,\,{{B}_{2}}=0\]

    Correct Answer: D

    Solution :

    At outer point algebraic sum of current is zero at inner point algebraic sum of current is not zero.
