Take the 2-minute tour ×  Does an accelerated charge always
radiate? For example the current electrons in an electric
circuit when moving through a turn they are accelerated, do they
radiate because of that acceleration?    1. If the answer is no,
then why not?   2. If the answer is yes, then how small the
radiation is? share|improve this question Can you clarify that
you're talking about synchrotron or cyclotron radiation? –

electron going around the loop would of course radiate. However,
if we have a constant current going around the loop, there are
many electrons and their individual radiations cancel each
other, so there is no net radiation. They balance each other
out. We can show their is no net radiation by solving Maxwell's
equations on the net current, which is constant.  There would be
some transient radiation when you change the current. Also, in
the real world, there would be some infinitesimal radiation due
to the fact that the current won
