  1. Electromagnetic interference happens when electronic devices such as FM radios, cell phones, CB radios and baby monitors interfere with each other's signals. For example, you may be able to intercept a CB radio message on your car's FM radio, or cause static on your computer when your cell phone is nearby. Although these devices are not supposed to interfere with each other, many transmitters can transmit at lower power on harmonic side bands. In daily life, these interruptions just annoy us, but they can become serious when electronic devices interfere with communications on an airplane or heart monitors at the hospital.
