Short for Electro-Magnetic Interference, EMI is a type of interference that occurs from invisible magnetic fields. These fields can cause interference in any type of electrical/electronic devices. For example: if you keep an electric fan near a computer monitor. you would notice that your monitor shows flickering or jumping picture signals due to EMI.

Radio Frequency Interference (RFI) is electromagnetic radiation which is emitted by electrical circuits carrying rapidly changing signals, as a by-product of their normal operation, and which causes unwanted signals (interference or noise) to be induced in other circuits. This interrupts, obstructs, or otherwise degrades or limits the effective performance of those other circuits. It can be induced intentionally, as in some forms of electronic warfare, or unintentionally, as a result of spurious emissions and responses, intermodulation products, and the like. It is also known as Electromagnetic Interference or EMI.

RFI frequently affects the reception of AM radio in urban areas. It can also affect FM radio and television reception, although to a lesser extent.

Most countries have legal requirements that electronic and electrical hardware must still work correctly when subjected to certain amounts of RFI, and should not emit RFI which could interfere with other equipment (such as radios).
