Reference [5] is an example of an earlier study on radiated electromagnetic noise propagation paths.
Electromagnetic noise usually has high-frequency components caused by a high frequency switching device of the power supply.
To PMSM, the electromagnetic force waves, caused by the interaction between rotor and stator harmonic magnetic flux density (the fourth item) and the interaction of various harmonic magnetic flux density produced by permanent magnet (the fifth item), are the major sources of electromagnetic noise.
It has already been reported that the display image on a personal computer (PC) that employs either a cathode ray tube (CRT) or a liquid crystal display (LCD) monitor using the raster scan method can be reconstructed by receiving and analyzing the electromagnetic noise [8,9].
BT says that the ADSL broadband speed that can be supported on an individual line is governed by a wide range of physical factors including the length and gauge of the line from the exchange, electromagnetic noise from other lines in a cable or wiring within a customer's premises and the modems used.
Due to regulations restricting electromagnetic noise emissions, electromagnetic compatibility (EMC) has become an increasingly important factor in the design of digital electronic devices and components.

This configuration eliminates electromagnetic noise. Delivering flow rates of 0 to 200 ml/min (liquid) or 0 to 7.5 scfh (gas) and pressures up to 12.5 psi, the pumps have a standard pump life of 10,000 hours.
This design eliminates electromagnetic noise, as there are no electric motors.
JM: The FCC filtering graphs are misleading and don't portray the potential issues: they do not address the impact of multiple devices communicating with each other, nor the potential aggregate effect to the electromagnetic noise floor.
The ocean is electrically very conductive and acts as a screen against electromagnetic noise - extraneous signals from other sources that would confuse interpretation of the data.
Because it is dielectric, fiber is immune to electromagnetic noise and ground loops, which cause a significant percentage of the downtime on copper-based networks.
