You can get an EMI detection device that will be able to locate exactly where EMI is being given off such as TV's Computers, Microwaves. A much easier way would be to look around for any medium or larged sized eletronic devices, they are most likely giving off EMI.
A simple way to detect EMI is to use an inexpensive AM radio into a low-frequency range next to the electronic device
Use a radio with AM. Turn the dial down to the lowest frequency. Then bring it close to the appliance that you want to check the EMI radiation. Turing that appliance on and off will produce a different noise pattern if EMI is emitted.
The simplest way is to use and inexpensive AM radio. Turn the turning dial away from a station and all the way down into low-frequency range. With the radio, you can hear the static that EMI produces.A+ Guide to Managing and Maintaining You PC. Andrews, JeanCh. 4 Pg. 159
