proximity effect

The proximity effect, like the skin effect, is a phenomenon of current displacement. This phenomenon is based on eddy currents and is limited to closely spaced conductors in which alternating currents

flow in opposite directions.

Proximity effect in closely

spaced conductorsAccording to the proximity effect, which is particularly pronounced at higher frequencies, high-frequency currents

tend to flow as close to each other as possible. Thecurrent flow is concentrated in the area where the two conductors are close to each other.

The proximity effect can be problematic for conductors and printed circuit boards because their effective conductor cross-section is further restricted. As a result, their AC resistance increases.
