What is that screechy sound produced when a cellphone is placed near a radio?

The loud static heard from the computer's speakers everytime the phone would receive a message or a call is due to electromagnetic interference or EMI. This is what happens when radio waves emitted by one device cause undesirable behavior in another. Thus, placing a cell phone near a computer may create network interference and a screechy sound or noise is often heard from the cell phone when it's trying to transmit or receive a signal.
