    A conducting circular loop of radius r carries a constant current . It is placed in a uniform magnetic field bq such that By is perpendicular to the plane of the loop. The magnetic force acting on the loop is

    A) \[\text{Ir}{{\text{B}}_{\text{o}}}\]                          

    B)  \[\text{2}\pi I\text{r}{{\text{B}}_{\text{o}}}\]

    C) \[\pi I\text{r}{{\text{B}}_{\text{o}}}\]                                   

    D)  zero

    Correct Answer: D

    Solution :

                     When a current carrying loop is placed m uniform magnetic field. \[\tau =0\] when \[\theta =0\], ie, when the plane of the coil is perpendicular to the field.
