    According to Maxwell?s hypothesis, a changing electric field gives rise to                                               [AIIMS 1998]

    A)            An e.m.f.                               

    B)            Electric current

    C)            Magnetic field                     

    D)            Pressure radiant

    Correct Answer: C

    Solution :

               According to the Maxwell?s EM theory, the EM waves propagation contains electric and magnetic field vibration in mutually perpendicular direction. Thus the changing of electric field give rise to magnetic field.
