    A vertical straight conductor carries a current upward. A point P lies to the east of it at a small distance and another point Q lies to the west at the same distance. The magnetic field at\[P\]is

    A)  greater than at Q

    B)  same as at Q

    C)  less than at Q

    D)  greater or less than at Q depending upon the strength of current

    Correct Answer: B

    Solution :

     Magnitude of magnetic field at any point due to a straight current carrying conductor depends only on the distance of the point with respect to current carrying conductor but not on the direction. Hence,\[{{B}_{P}}={{B}_{Q}}\](at same distance).
