Are EMFs emitted from the Juan de Fuca Cable?
DC cables do not generate fluctuating EMFs. The static magnetic field surrounding a DC cable is weak, and the strength of the field falls off rapidly with distance from the cable. The strength of magnetic fields is measured in units of “Gauss”. Naturally occurring magnetic fields, such as that of the Earth, are relatively weak and are measured in milli-Gauss (1 milliGauss is 1/1000 of a Gauss). In the Pacific Northwest, the Earth’s magnetic field strength is roughly 570 milliGauss. Since the JdF Cable will be buried to a depth of 1 to 2 metres (3 to 6 feet), the field strength for someone standing on the ground directly above it will be only slightly more than the Earth’s natural magnetic field. As their distance from the cable increases, the field strength falls off rapidly. To put this field strength in perspective, the International Commission on Non-Ionizing Radiation Protection (ICNIRP) has established protection guidelines for general, continuous, public exposure to static (DC) f
