    A uniform magnetic field, parallel to the plane of the paper existed in space initially directed from left to right. When a bar of soft iron is placed in the field parallel to it, the lines of force passing through it will be represented by [CPMT 1986, 88]           

    A)            Figure                                     

    B)            Figure

    C)            Figure                                     

    D)            Figure

    Correct Answer: B
