Electrons in wires generally move far far far too slow to produce synchrotron or cyclotron radiation at a radiofrequency and while I'm not 100% sure I believe that a uniform current in all parts of the loop would remove this effect. DC is still DC if pulsed and will create radiowaves.
Many years ago, before ipods and mp3 players, I had a sony walkman with a radio turner. I found that if a pocket calculator were switched on and placed on top of the walkman I could move the tuner's dial to particular frequency and hear a faint "thump.......thump.......thump..." sort of like a heartbeat. Different calculators generated a similar pattern of sounds. What was going on? Harry
