What is Electromagnetic Interference (EMI)?

Electromagnetic Interference causes the altering of an electrical waveform and direction of an electron path due to an interaction with a strong intercepting or coupling electromagnetic field that has a different frequency.

  1. What is Electromagnetic Interference (EMI)?

  2. Electromagnetic Interference causes the altering of an electrical waveform and direction of an electron path due to an interaction with a strong intercepting or coupling electromagnetic field that has a different frequency.

  3. Four Types of Electromagnetic Coupling 1. Inductive Coupling : Inductive Coupling occurs when a strong electromagnetic force, or EMF, intersects an electrical conductor within a magnetic field, causing the first magnetic field to become distorted. 2. Conductive Coupling : Conductive Coupling occurs when the coupling path between the source and the receptor forms a direct electrical contact with a conducting body.

  4. 3. Capacitive Coupling : Capacitive Coupling occurs when two fluctuating electrical fields co-exist between two adjacent conductors, thereby inducing a change in voltage on the receiving conductor, or receptor. 4. Radiative Coupling : Radiative Coupling occurs when there is a distance exceeding one wavelength between the source point and the receptor. For more info, you can consult with our EMI Specialist

  5. How Does EMI Occurs Metal, of course, is a conductor for electromagnetism. If you have a strong electromagnetic field nearby a metal wire that has an electrical current and/or voltage, the nearby electromagnetic field will magnetically converge, couple, and ride along with the original current. Imagine a surfer hopping onto his surfboard to ride that perfect wave.

  6. The amount of interference that will occur on an electronic is relative to frequency, the V/m (Volts per meter) and the magnetic flux of the intruding EMF.
