Where Does Electric Magnetic Interference Come From?

EMI (Electromagnetic interference) can disrupt the functionality of electronic equipment. In a worst-case scenario, electronics seize to function as a result of excessive EMI. It is vitally essential for electronic engineers to consider causes of electromagnetic influences. Using EMI shielding and EMI gaskets are the best way to manage problems of external EMI.

What causes EMI?

There are two primary sources for EMI. This includes natural and human-made EMI.

The most common cause of Natural EMI includes:

• Lightning
• Solar Magnetic Storms
• Earth’s Magnetic Field Flux
• Cosmic Radiation

Most causes of natural EMI do not pose significant threat levels to electrical equipment. The most prominent causes of EMI are human-made. Human EMI includes:

• Hand-help Electronics
• Power Lines
• Computer Circuits
• Motors

Some EMI comes from within the machine that is being used. It is essential to recognize the different electronics within a single structure because they can affect each other. For instance, a car or truck has multiple electronics inside of it. Between Bluetooth, the radio, and other computer chips, there is a great deal of EMI being created all within a single car.

EMI Shielding

Regardless of the cause of EMI, it still negatively affects the performance of electronics. Be smart and protect your equipment with EMI shielding and EMI gaskets. For more information about customized shields and gaskets, you should give our team a call.
