The following error was encountered while trying to retrieve the URL: http://drt-checker.com/links/getlinks.php technical article, I wrote about electrical noise occurs or is transmitted into a signal cable system in the following four ways:

Galvanic (direct electrical contact) – part 1
Electrostatic coupling – part 1
Electromagnetic induction
Radio frequency interference (RFI)

3. Magnetic or inductive coupling

This depends on ; } #dirlisting tr.entry td.icon,td.filename,td.size,td.date { border-bottom: groove; } #dirlisting td.size { width: 50px; text-align: right; padding-right: 5px; } /* horizontal lines */ hr { margin: 0; } /* page displayed footer area */ #footer { font-size: 9px; padding-left: 10px; } body :lang(fa) { direction: rtl; font-size: 100 the rate of ; margin-right: 2 change of the noise current and the ; } /* Page displayed body content area */ #content { padding: 10px; background: #ffffff; } /* General text */ p { } /* error brief description */ #error p { } /* some data which may have caused the problem */ #data { } /* the error message received from the system or other software */ #sysmsg { } pre { font-family:sans-serif; } /* special event: FTP / Gopher directory listing */ #dirmsg { font-family: courier; color: black; font-size: 10pt; } #dirlisting { margin-left: 2 mutual inductance between the noise system and the signal wires.

Expressed slightly differently, the degree of noise induced by magnetic coupling will depend on the:

Magnitude of the noise current
Frequency of the noise current
Area enclosed by the signal wires (through which the noise current magnetic flux cuts)
Inverse of the distance from the disturbing noise source to the signal wires.
