In this age of technology and advanced gadgets, we often hear the term 'EMI' in various contexts. But what exactly is EMI, and how does it impact our lives? EMI or Electromagnetic Interference is a phenomenon where electrical disturbances or electromagnetic waves generated by different devices disturb the functioning of other electronic devices around them. This article aims to provide an in-depth understanding of EMI, its types, sources, and how it affects our lives.
What does EMI mean?
In simple words, EMI refers to the degradation or disruption of the proper functioning of an electronic device caused by unwanted electromagnetic waves. Electromagnetic waves are waves of energy that travel through the air or space at the speed of light containing electrical and magnetic fields. When the electrical current passes through an electronic device, it generates waves that radiate into the surrounding. If other electronic devices are present in their vicinity, these waves could affect their functioning, leading to EMI.
Types of EMI
EMI is classified into two categories: radiated EMI and conducted EMI.
Radiated EMI
Radiated EMI occurs when an electronic device generates electromagnetic waves and radiates them into surrounding space, disrupting the functioning of other devices. This is a common form of EMI and is most visible in the form of static noise on your radio or TV.
Conducted EMI
Conducted EMI occurs when the electromagnetic waves generated by an electronic device are conducted through electrical wires leading to the device. For example, household appliances such as a washing machine could result in conducted EMI, as they consume high voltage power and generate electromagnetic waves that could travel along the supply wires and cause interference with other devices that share the same electrical circuit.
Sources of EMI
EMI can be generated from various sources, including natural sources, electronic devices, and even man-made electrical infrastructure.
Natural sources
Lightning is a naturally occurring source of EMI as it generates high-energy electromagnetic waves that could interfere with electric systems from a distance.
Electronic Devices
Electronic devices such as mobile phones, laptops, and desktop computers generate EMI in the form of radio waves that could disrupt the functioning of other devices such as FM radios or other communication devices.
Man-made infrastructure
Electrical power lines and transformers are the most common source of EMI, as they generate strong electromagnetic fields that spread over a wide area. The electrical infrastructure such as transmission lines and transformers used to distribute electrical power could cause massive disruption in communication systems, especially when they are placed in the immediate vicinity of such infrastructure.
How EMI Affects our Lives?
EMI could affect our lives in a variety of ways. It could be a cause of serious concern, especially when it affects critical systems such as airplanes, hospital equipment, and military communication systems. Below are some of the common effects of EMI:
Degradation of sound quality
One of the common effects of EMI is the degradation of sound quality. This could result in the hissing on a radio or static noise on a speaker.
Interference with electronic equipment
EMI could interfere with the functioning of electronic equipment by reducing their efficiency and leading to errors in the device.
Data loss
Data loss could occur as a result of EMI, especially if the device's storage capacity is overloaded or if the device is not properly grounded.
