1. The problem statement, all variables and given/known data Which of the following will produce Electromagnetic radiation? Explain Your answers. a) Alternating current in a TV transmitter b) The cord of a vacuum cleaner while it is being used c) The circuit of a battery operated CD player d) A positively charged particle travelling around a cyclotron e) The wire connecting a DC light globe to a power pack 2. Relevant equations 3. The attempt at a solution a) YES. The oscillating electrons produce a radio wave. b) YES. The AC current in the cord produces EM radiation. c) maybe. The electrons go round in the circuit but does that produce EM radiation? d) maybe. Same as c) except protons. Not sure. e) NO. As it is direct current there is no oscillating electrons and therefore no EM radiation. Are these right? Please help with c) and d) as well, I'm really not sure. Thankyou.
