    Do you mean why does an accelerated charge radiate?

    yes, you're right~

    This can only be seen in a detailed derivation of the radiation E and B fields.
    See almost any intermediate or higher EM text.
    The key point is that, for raditation, E and B fall off like 1/r instead of 1/r^2.
    This follows from the use of the retarded time.
    It turns out that if the velocity is constant, the retarded time does not result in the 1/r dependence.
