Faraday’s Principle and EMI Filtering

Electromagnetic Interference (EMI) is a common challenge in today’s electronic devices, often leading to performance issues and signal disruptions. To combat this, engineers turn to Faraday’s Principle and employ EMI filtering techniques. In this article, we delve into the intricacies of Faraday’s Principle and its crucial role in effective EMI filtering. Faraday’s Principle: A Brief Overview Michael Faraday, a pioneering scientist in the 19th century, laid the groundwork for understanding electromagnetic induction. His eponymous principle states that a change in magnetic field within a closed loop induces an electromotive force (EMF) in the conductor encircling the magnetic field. This principle serves as the foundation for numerous applications, one of which is mitigating EMI. EMI and Its Impact Electromagnetic interference arises when unwanted electromagnetic signals disrupt the normal functioning of electronic circuits. This interference can originate from various sources, includin...

How an EMI Filter Works

Introduction Electromagnetic Interference (popularly known as EMI) can be defined as the interference caused due to the electric or magnetic field that affects (degrades or damages) the signal strength, the component, and the functionality of the electrical device. It encompasses RF (Radio Frequency) interference. EMI can be classified into two broad areas, namely Narrowband emission and Broadband emission.   Narrowband emission  is generally man-made whereas  broadband emission  may be either natural or man-made. As the name suggests, narrowband emission is only limited to a small area of the radio spectrum, while broadband emission affects a large area of the electromagnetic spectrum. Narrowband emission may be continuous or sporadic, whereas broadband emission is a one-time event that is random, sporadic, or continuous. Power lines generate hum sound (i.e., narrowband emission), while lightning strikes generate broadband emission. EMI Sources Electromagnetic inter...

What are the Main Causes of Electromagnetic Noise

Electromagnetic Interference (popularly known as EMI ) is an electromagnetic/electrical disturbance that causes the malfunctioning or degradation of electrical equipment. It can not only lead to the loss of transmitted data, but it can also damage the equipment completely.  Despite all the disruptions caused due to EMI, it is common in the modern environment. EMI occurs due to natural causes as well as human-made electrical devices. Human-made EMI results due to electrical/electronics circuits, switching systems, or changes in large amounts of current. Human-made EMI occurs in both the residential and industrial sectors.  Let’s understand the causes of electromagnetic noise in detail. Natural Causes A variety of sources that lead to natural causes of EMI are the sun, dust storms, lightning strikes, snowstorms, solar flares, static electricity, solar magnetic storms, cosmic noise, and atmospheric electrical storms. The sudden occurrence of natural EMI creates a severe impact on...
