    According to Maxwells hypothesis, changing electric field gives rise to:

    A)  magnetic field                 

    B)         pressure gradient          

    C)         charge                                

    D)         voltage

    Correct Answer: A

    Solution :

    From Maxwells electromagnetic theory, the electromagnetic wave propagation contains electric and magnetic fields vibrating perpendicularly to each other. Hence, changing of electric field gives rise to magnetic field.
