    The vertical component of earth's magnetic field is zero at or The earth's magnetic field always has a vertical component except at the [NCERT 1980, 88; CPMT 1983; MP PMT 1996]

    A)            Magnetic poles                   

    B)            Geographical poles

    C)            Every place                           

    D)            Magnetic equator

    Correct Answer: D

    Solution :

               At magnetic equator, the angle of dip is 0o. Hence the vertical component \[V=I\sin \varphi =0.\]
